1)

A quantity of n moles of oxygen gas (CV = 5R/2 and Cp = 7R/2) is at absolute temperature T. You increase the absolute temperature to 2T. Find the change in internal energy of the gas, the heat flow into the gas, and the work done by the gas if the process you used to increase the temperature is isochoric.

Express your answers in terms of the variables n, R, and T separated by commas.

2)

Find the change in internal energy of the gas, the heat flow into the gas, and the work done by the gas if the process you used to increase the temperature is isobaric.

Express your answers in terms of the variables n, R, and T separated by commas.

3)

Find the change in internal energy of the gas, the heat flow into the gas, and the work done by the gas if the process you used to increase the temperature is adiabatic.

Express your answers in terms of the variables n, R, and T separated by commas.
