Q1:

Find the change in the internal energy of the gas.

Find the work done by the gas.

How much was the gas heated by the heat bath?

Q2:

1.00 mol of an ideal gas at a pressure of 3.00 atm and a temperature of 300 K expands isothermally to exactly triple its volume. What is the work done by the gas due to its expansion?

Q3:

In an isothermal reversible expansion of an ideal gas at a temperature of , the gas does 25 J of work. What is the entropy change of the gas?
