Name________________________________ Kinetic Theory of Gasses 1) An ideal gas is enclosed in a constant volume container. The pressure of the system is 1.5 atm, volume is 2.5 liters and the temperature is 30 o C. a) Determine the # of moles of gas enclosed in the container. b) Determine the average KE of the molecules. c) If the gas is helium, determine the v rms speed of the molecules. (The molar mass of helium is 4.0 x 10 -3 kg/mole) d) If the temperature of the system is increased to 100 o C, determine the pressure. e) How many molecules are there in the container? f) What is the total energy of the gas now that the temperature was increased to 100 o C? g) If the pressure is increased to 7 atm, determine the temperature of the gas at constant volume.
