Three moles of oxygen gas (O2) are placed in a portable container with a volume of 0.0037 m3. The temperature of the gas is 330°C.

Question

(a) What is the pressure of the gas?
? Pa
(b) What is the average kinetic energy of an oxygen molecule?
? J

Answer 1

a) Use the ideal gas law to find pressure
PV=nRT

b) avgKE= 5/2 k T where the 5/2 is used for diatomic gases, and k is Bultmann's constant.
