Research: Ice is frozen water. The state of matter ice is at in room temperature is liquid. When the temperature of water comes below a certain point, called the freezing point, it starts to solidify. The freezing point of pure water is 32 degrees Fahrenheit, but when water comes into contact with different substances the freezing point can sometimes move up or down. Salt is a white crystalline substance that gives seawater its characteristic taste. The chemical formula for table salt is sodium chloride

Discussion and Conclusions Discussion: Part 1 experimental data were obtained by identifying and determining the purity of unknown #1. The start and end temperature for unknown #1 was 136-137.8 degree Celsius using the fast ramp. We used the slow ramp twice to find a more accurate melting point range for unknown #1. The first melting point range was 132.8-133.6 degree Celsius. The second melting point range was 131.9-133.4 degree Celsius. We now know that unknown #1 is Urea, which has a known

RESEARCH DESIGN FOR RICE HULL AS AN ALTERNATIVE SUBSTITUTE CHARCOAL Submitted By: John Paul Apolinario Jose Ramil Gaña Eugene Denamarca Introduction: This is the research design for the comparative/experimental study named as “Rice hull as an Alternative Substitute to Coconut Charcoal”. This contains the blueprint of the tests needed to conclude whether Rice hulls can equal or surpass Coconut as charcoal in different aspects. Test 1: In this test, we will compare the

Conclusion In the starting of the experiment, we construct a body of the water rocket, which is made out of unwanted bottles. Other than that, we used wood plank, PVC tube, wire holder and bicycle tire to build the water rocket launcher After conduct this experiment, we found that heat will affect the temperature change. The time taken for the water rocket launched into the air and drop to the ground is longer. Hence, the

Amit Gorajia March 7, 2014 Our Diverse Biosphere Essay 2 Adapt or Perish Scientific studies show that the increase in temperature is responsible for roughly half of the total amount the sea level has risen in the past century. This raised concern for certain coastal regions that may have to endure more natural disasters such as floods and hurricanes. However, humans are not the only species that are affected by the increasing in temperature. One species that may be potentially affected greatly

into an area to the side of the capillary. The scale allows the temperature to be read off in units of degrees. The type of degree unit depends upon the specific thermometer. Two commonly used temperature scales, are degrees Celsius and degrees Fahrenheit, which are found on everyday thermometers. An alternative scale that measures temperature in degrees Kelvin is often used by scientists and engineers. The Bulb A swelling, or bulb, at the bottom of the thermometer stores the mercury used in calculating

The highest elevation was in 1986 at 4,212 feet above sea level. The surface terrain at the Great Salt Lake is sandy, rough, rocky, and kind of grassy.The wetlands are different than deserts because the deserts are humid, hot, and dry, and the

respond to 15 degrees Celsius? Blood vessels contract near surface. Muscles contract (shiver) When would heat stroke occur? Heat stroke occurs when the body over heats. Heat stroke occurs when the core body temperature is greater than 105 degrees Fahrenheit (40.5 degrees Celsius), with complications involving the central nervous system that occur after exposure to high temperatures. Primary hyperthermia (for instance, heatstroke), temperature regulation is either partially or totally out of action

Investigation Plan PROBLEM Does sugar, salt, and baking soda affect the boiling point of water? HYPOTHESIS My hypothesis is that those materials will not affect the boiling point. PROCEDURE To begin my experiment, I will buy a measuring cup, baking soda, and thermometer at a grocery store. The measuring cup will measure to a cup, and the thermometer will be a glass thermometer so it will not break when water gets hot. In a pot, I will take two cups of tap

The average temperature for the environment covered with no microscope slides was 33.4 C, the average temperature for the environment covered by 1 slide was 33.2 C and the average temperature for the fully enclosed, taped box (environment) was 32.2 C. The collected data appears to show almost the opposite of what was predicted by the hypothesis (the hypothesis predicted that the fully enclosed environment would be hotter than the opened/uncovered environments). Evidently the hypothesis was proven
