[QUOTE="hairey94, post: 6356957, member: 679296"] [B]Homework Statement:[/B] The pressure of a 0.02 m3 monoatomic gas in a container is 2 atm. The mass of each atom is 3.351 x 10^-23 g. Calculate the average translational kinetic energy of the gas. [B]Relevant Equations:[/B] Ktr = (3/2) (R/NA) T = (3/2)kT U = NKtr = (3/2) nRT = (3/2)NkT If this question asked for internal energy, then it is a straightforward thing, just use the formula U = (3/2) nRT = (3/2) PV. But the question specifically asked for average translational kinetic energy which I'm stuck with the value of T to plug in into the formula as the question only give us P and V. So no value for n and T. [/QUOTE]
