1 Gas Laws At constant temperature, all gases behave the same when compressed As increasing pressure is applied to a gas in a closed container, the volume of the gas decreases he product of pressure and volume is always constant P 1 V 1 = P 2 V 2 P. V = k Why does the plunger bounce back? Use the terms: particles collisions Walls of container plunger he gas in a balloon has a volume of 7.5 L at 100 kpa. he balloon is released into the atmosphere, and the gas in it expands to a volume of 11 L. Assuming a constant temperature, what is the pressure on the balloon at the new volume? List what you know Write the formula Solve for the variable you need Plug 'n chug P 1 V 1 = P 2 V 2 1 atm = kpa 70 kpa = Standard Pressure (at sea level) = 70 kpa Graph Jacques Charles discovered that the volume of a gas is directly proportional to its temperature (Kelvin scale) At constant pressure, the volume of a gas divided by its absolute temperature is constant.
