...3INT Task 3 1. Problem statement How does salt have an effect on freezing point of water? 2. Relevance of your testable question When salt is added to water it results in the reduction of its freezing point and the density of water increases. Freezing point depression which is a colligative property does not depend on its solute character rather it depends only on its solute concentration. 3. Literature review Entropy is frequently defined as a quantitative measure of randomness. When a solute is dissolved in a solution similar to water, the entropy of the solution increases. Freezing becomes extemporaneous when the extent of heat energy lost by the water during freezing is equivalent to the temperature times the reduction in entropy linked with freezing (Brennan, n.d.). Water freezes and melts at 0°C (32°F). However, dissolving any substance in pure water lowers the freezing point. A water with very high salt level such as highly saline lake waters at Death Valley, California (nearly 300,000 units per million "salt") may freeze and melt at temperatures as low as -20 to -30°C. As salt lowers the freezing point depression, it is used on icy roads and highways in order to melt the ice (Benison, 1998). The reason why salt lowers the freezing temperature of water can be explained as follows: When liquid pure water reaches its freeze point and becomes ice, the water molecules form themselves into an ordered formation. Salt...

...A. Complete a Project Design 1. Literature Review a. Physics of Paper Airplanes (www.exampleessays.com essay) This paper is about the things needed to make a paper airplane fly. There are many things that contribute to a planes ability to fly. Some such things are weight, velocity, lift, and drag. Weight is relevant because the weight is directly related to gravity. In order to make the plane fly better it stands to reason that it needs to be lighter so that the pull of gravity will not be as great. Velocity is the initial push the plane gets when it is released. The greater push it is given the longer it will stay in flight. Velocity is directly affected by drag, which is the friction in the air that it is flying through. The lift is what keeps the plane flying and is created when flow is present. Flow is a current of air that is either flowing with or against the airplane, and this direction affects how far the airplane will fly (www.exampleessays.com, 2012). This paper is relevant to my experiment because in order to create a proper testing area, it is important to know what effects the environment will have on the plane. In addition to that it puts the question as to would it really matter what kind of paper was used for the plane? Would that slight difference in weight of varying types of paper really make a difference in a controlled environment on how far the paper airplane would fly? My hope is to find an answer to that question with my experiment...

...California. With a magnitude of 7.8. The quake affected 375,000 square miles. It could be felt all the way to Nevada. One half of this miles were in the Pacific Ocean. The cities of San Jose, Santa Cruz, and Santa Rosa were all affected by this earthquake. There was 400 million dollars, 1906 dollars, in damages done to the city. This was the first major disaster in the world to be documented by pictures. Slide 2 The Fires The fires erupted after the quake. Firefighters were unable to fight them because the water lines were destroyed in the quake. 28,000 building were destroyed spanning over 500 blocks. The fires burned for 3 days. As a result they caused more damages then the quake did. 225,000 people lost their homes and 3,000 perished. The city built refugee camps to house the ones who lost their homes. Slide 3 History Theodore Roosevelt was the current president, being elected in 1901. In December of 1906, president Roosevelt was awarded the Nobel peace prize for his help with the peaceful end to the Russo-Japaneese war. In 1906, 1.1 million immigrants had arrived in America. That is the most to arrive on a single year. At this time San Francisco was the 9th largest city in the United States. The night before the quake, Italian tenor, Enrique Caruso played at the Palace Hotel. The hotel was destroyed the next day due to the fires. Slide 4 A New beginning It took 9 years to rebuild the city. Though they were quick to start...

...Project Design Plan The experiment is designed to test how the degree of inflation in a basketball directly relates to its rebound height. My intent is to determine how the air pressure can negatively affect the ball with too short or high a rebound. This is relevant to basketball players because they need to maintain control over the ball. Too little inflation and the ball will not bounce high enough for them during dribbling to continue forward at maximum speed to score or they will not be able to pass the ball on a bounce because the ball may not make it to the next player. Too much inflation and the ball may become erratic and not go where it is intended during a pass and will be much more difficult to handle while dribbling. Literature Review The NBA (National Basketball Association) is the governing body for professional basketball in North America. In order for a basketball to meet regulation standards for professional games, the NBA states on page ten of their rule book in section II.f.(1) “ The ball shall be an officially approved NBA ball between 7 ½ and 8 ½ pounds of pressure” (National Basketball Association, 2013). The NCAA (National Collegiate Athletic Association) states in its rulebook in section 16, article 7 that “when [the ball] is dropped to the playing surface from a height of 6 feet measured to the bottom of the ball, it will rebound to a height, measured to the top of the ball, of not less than 49 inches when it strikes its least resilient spot nor...

...one tablespoon of salt to the boiling water at two separate points. The first when the water first came to a boil and the second when the temperature steadied after adding the first tablespoon of salt. The outcomes did show an increase in the boiling temperature. First raising it from the 212.9 degrees F to 215.6 degrees F and then 218.3 degrees F. The second study I used looked at the starting temperatures of water to see if hot or cold water would come to a boil faster. Their hypothesis was that hotter water would boil faster than colder water because it is closer to the boiling point of 212 degrees Fahrenheit. The study used 3 cups of water in their experiment and they used hot tap water and cold tap water with the room temperature at 69 degrees F. It was found that the hot tap water boiled faster than the cold tap water. The hot tap water took 3 minutes four seconds to come...

...Stephen Rueden INT1 Task 3 Sub domain 114.1.1 Scientific Concepts, Theories & Inquiry 4/17/2011 Literature Review: Elasticity and Hooke’s Law: In physics, elasticity is the physical property of a material that returns to its original shape after the stress that made it deform is removed (Elasticity, para. 1). Elasticity was first studied in the late seventeenth century by the English scientist Robert Hooke (16351703). He made observations about elasticity using metal springs and eventually developed what is known as Hooke’s Law: The restoring force exerted by an elastic object is proportional to how far it has been distorted from its equilibrium state. Everything we associate with springs, has some place in the behavior of balls (Bloomfield, p.69). When a ball or a spring returns to its equilibrium state, it releases stored energy. Isaac Newton and the Law of Universal Gravitation: Isaac Newton (16431727) studied gravity and its effects on falling objects. He is most famous for the three laws of motion. Newton’s law of universal gravitation states that every point mass attracts every single other point mass by a force pointing along the line intersecting both points. The earth’s gravity exerts a downward force on the ball, called the ball’s weight. Its weight causes the ball to accelerate downward (Bloomfield p. 10). Reasoning: What does elastic mean? When a rubber band gets stretched it returns to its original shape. What is something that is not elastic? When a piece of...

...hardware and system software in the data centers that provide those services [2]. OR type of parallel and distributed system consisting of a collection of interconnected and virtualized computers that are dynamically provisioned and presented as one or more unified computing resources [3].Cloud computing purely relies on the fact that sharing computing resources rather to have applications on local servers or devices if resources are not equally distributed then this will result in resource wastage. The cloud computing platform guarantees subscribers that it sticks to the service level agreement (SLA) by providing resources as service and by needs based on the broker policy[4]. So in order to get maximum benefit from cloud computing there is need to dynamically balance the load among servers and improve utilization of resources. There are still some areas that are needed to be focused on in cloud computing. Resource Management Task Scheduling The task scheduling goals of Cloud computing is provide optimal tasks scheduling for users, and provide the entire cloud system throughput and QoS at the same time.

...INT Task 3, 4-25-2015 Popcorn Experiment Lakshmi Prakash Project Design Plan Popcorn is a popular treat for individuals. It is made up of dried corn kernels that have the ability to pop when activated by heat, yielding a soft, but crunchy snack. Popcorn can be made over the stove or in a microwavable bag. When the corn kernel is brought to a heat temperature of a boiling point, steam is formed from the water inside the kernel, this causes an intense pressure inside the kernel. Because the outside of the kernel is strong, it’s able to hold and capture the steam inside, which then quickly explodes and turns inside out. This is where we get the soft, but crunchy snack. Literature Review There are many brands of popcorn readily available at the grocery stores. There have been quite a few experiments done to test which one is the best in terms of producing the most amount of popped kernels. Sean Boyd did an experiment, titled “The Jawbreakers of the Popcorn Industry,” where he tested a total of 5 different brands of popcorn to see which one would produce the most kernels. He performed the experiment 3 times on each brand and it was successful. His hypothesis was incorrect, but it yielded an answer that Oroville popcorn was not the best popcorn, but that another brand was. I am using a similar method in my experiment, but based on his results I did not choose Oroville to be the leading popcorn brand (Boyd). Barbara Bolz wrote an article as to why popcorn...

...Task 1 LO 1.1 All high-level programming languages support the concept of data types. A data type defines a set of values that a variable can store along with a set of operations. Data types are used to store various types of data which is managed by program. Data type attaches with variable to determine the number of bytes to be allocate to variable and valid operations which can be performed on that variable. Although C has several built-in data types, it is not a strongly typed language, as are Pascal and Ada. C supports various data types and here some common data type as character, integer and floating-point types. C defines five foundational data types as defined below: ▪ character ▪ integer ▪ floating-point ▪ double floating-point ▪ valueless These are declared as by char, int, float, double, and void, respectively. These types form the basis for some other types also. The extent and choice of these and data types may contrast amongst processor natures and compilers. However, in all belongings an object of type char is 1 byte. C stores character type inside as an integer. Each character has 8 bits so, we can have 256 different characters values (0-255). Character set is used to map between an integer value and a character. The size of an int is ordinarily the same as the word length of the implementation setting of the program. C has 3 classes of integer storage namely short int, int and long int. All of these data types...
