When 597 J of heat are added to a gas, it expands. Its internal energy increases by 318 J. How much work does the gas do? (Be careful with +and - signs. +Wexpansion, +Q-added, +AU temp goes up.) (Unit J)
7. A 0.2 moles of diatomic gas are contained in a cylinder at 300 K and atmospheric pressure 1*10^5 Pa. The gas receives 1000 J of heat in an ideal adiabatic transformation. Calculate the change of internal energy, the work done on the gas and the final volume and temperature of the gas.

A classroom has a volume of 165 mA3. How many moles of gas are in the room if the temperature is 20.0° C and the pressure is 1.00 atm? (Make sure to put P, V, and T in the right units.) (Unit mol)
1. Ideal gas with internal degrees of freedom. Consider a free gas of diatomic molecules at temperature 7. Diatomic molecules have internal rotational excitations. The rotational energy levels of a single molecule are given by J(J+1) 2/2 J = 0,1,23 where J is the angular momentum and I is the moment of inertia. The degeneracy of the level J is 2J +1. Neglect any interaction between the molecules in the gas. The temperature is high enough so that the statistic...
