A 15.0-L tank containing 1.0 mol of argon gas is at 298 K.

(a) Calculate the initial pressure of the gas and d, the length of the cube containing this volume.

(b) Using your value for d, calculate the energies of the two lowest translational energies for the system E1,1,1 and E2,1,1 and their differences ΔE .

(c) The tank is opened and the gas is allowed to expand rapidly into a cubical 2000L room such that there is no heat exchange with the surrounding.

Assuming n2,1,1/n1,1,1 remains constant, Determine the new temperature of the gas.

Handwritten answers are preferred.
