Homework this week: 1.5b, 1.7ab Quiz 2: 1.4c, 1.5b, 1.7ab 1. Solving Formulas A formula is an equation which represents the relationship between two or more variables. Example 1.1. (1) The formula x = y means that x and y are the same. (2) The formula C = 5 (F − 32) represents the relationship between temperatures in 9 degrees Fahrenheit F and Celsius C. A formula is called solved for one of its variables if that variable is isolated on one side of the equals sign in the equation. Not all formulas

Title: Specific Heat of a Metal Purposes: Be able to measure specific heat. Be able to use a calorimeter correctly. Be able to find and measure the specific heat of a metal. Calculate the change in water temperature. Hypothesis: The specific heat of the metal sample (lead) will be very low. Safety: goggles, apron, hair restraints, Bunsen burner, heated water, harmful metals, breakable glass containers Materials: goggles and apron, beaker (250 mL or 400 mL) , hot plate/burner with ring stand,

10 SCIENCE SAYINGS “The whole of science is nothing more than a refinement of everyday thinking.” -Albert Einstein “Science is a way of thinking much more than it is a body of knowledge.” -Carl Sagan “No amount of experimentation can ever prove me right; a single experiment can prove me wrong.” -Albert Einstein “In all science, error precedes the truth, and it is better it should go first than last.” -Hugh Walpole “Science is simply common sense at its best, that is, rigidly accurate

Ladies and gentleman we need your help. Today I want to talk about the facts, disperse the myths and highlight the many ways we can help save our planet. Our planet is slowly dying right beneath our feet. Our planet has risen 0.6 of a degree for the past ten years. The United Nations panel has predicted that the temperature will rise 3-10 degrees Fahrenheit by the century’s end. Yet we are still burning coal and oil the two of the world’s most top reasons why global warming is happening. If we do

With correlation and regression scores on x and y must be disturbed and there must be a linear relationship between x and y. Ho: There is no relationship between feelings towards the bible and religious service attendance. My alternative hypothesis is: H1: There is a strong relationship between those with feelings towards the bible and religious service attendance. Based on my findings there is a significant correlation between the two variables, so I would reject the null hypothesis

The Control of Microbial Growth Chapter 7 I. Killing Microorganisms: Microbial control practices have been developed to reduce food spoilage and the incidence of disease. A. Controlling Growth: * Sterilization: destruction or removal of all pathogens (even spores) * Difficult to accomplish * Not always necessary * Requires harsh treatment * Disinfectant: destruction of vegetative pathogens (but not spores) * Chemical is a disinfectant * Antiseptics:

Chemistry Lab Chemistry Lab Aim: To investigate the specific heat capacity of water, copper and aluminium by using a caloriometer. Results: 1. Ohms Law: I=v/r, equation 3 = E=vlt hence you get E= v2t/r when ohms law is applied to equation 3. 2. De ionized water is used as it is the purest form of water, as it doesn’t contain ions from the soil like normal water which allow the conduction of electricity as normal water allows electrons to flow, thus preventing any extraneous variables

Essay on Pro Global Warming I believe that Global Warming has been here since we first started using machines, which used steam engines or combustion engines. The first type of wheeling automobile was made in 1769 that is about 250 years ago. So since the first type of ‘car’ was invented so much time ago, then we can assume that there has been carbon dioxide, smoke and steam in the atmosphere. When this happens the atmosphere breaks into little holes, through those holes the rays of the sun pass
