“THE GAS MAN COMETH” The documentary‚ “Gas Land”‚ by Josh Fox‚ is a film about the problems with contaminated groundwater due to excessive and unregulated natural gas extraction across the country. In the film‚ Fox travels all over to talk to many people who have rented out their land to natural gas companies‚ only to get contaminated water and no help from any company or organization with the problems that ensue. Fox uses many techniques in his film to get across his point that America should

Ideal Gas Law: The ideal gas law is the equation of state of a hypothetical ideal gas. It obeys Boyle’s Law and Charles Law. Ideal Gas Law Formula : General Gas Equation: PV = nRT Pressure(P) = nRT / V Volume(V) = nRT / P Temperature(T) = PV / nR Moles of Gas(n) = PV / RT where‚ P = pressure‚ V = volume‚ n = moles of gas‚ T = temperature‚ R = 8.314 J K-1 mol-1‚ ideal gas constant. Ideal Gas Law Example: Case 1: Find the volume from the 0.250 moles gas at 200kpa and 300K temperature

their gills only allow them to take in oxygen from the water. The percentage of oxygen is the water is significantly lower than the amount of oxygen in the air. Fish have adapted to be able to filter oxygen from the water despite its low percentage. Gas exchange in fish occurs in their gills which is supported by a bony arch. Fish take water in through their mouths. Water enters via a fish’s open mouth‚ its opercula close and stop water from leaving before being forced through the gill filaments. Once

How Much Gas is Produced? Julie Dang June 23‚ 2013 Purpose The Company ABC Chemical has asked our group to investigate the gas production from a number of various chemical reactions. The company would like us to measure the amount of product we get when we measure the amount of gas from two reactions. We will then compare our data to the predicted amount which will we will calculate based of the Law of conservation of Mass and Ideal Gas Laws. Methods Materials Thermometer CaCO3

________ Page 1 Name ______________________ Evaluation of the Gas Law Constant Objectives In this experiment‚ we will determine the Ideal Gas Constant‚ R‚ which relates the number of moles of gas present to its volume‚ pressure and absolute temperature. Background To see how "R" was derived‚ we must look at the proportionalities defined by the other fundamental gas laws. For example‚ Charles’ Law showed us that the volume of a gas sample is proportional to its absolute temperature at constant pressure

Chemistry 1061: Principles of Chemistry I Gas Laws Gas Laws: Pressure‚ Volume‚ and Temperature Introduction Pressure‚ volume‚ and temperature are properties of gases that reveal their relationships when any one of them is varied. Changing the temperature of a gas may change its volume or pressure‚ but how? What are the mathematical relationships between these properties? Are there limits to them? Scientists have discovered through the study of properties of gases that there is indeed a theoretical
