Which of the following statements is correct? The internal energy of a system increases when more work is done by the system than heat was flowing into the system. The internal energy of a system decreases when work is done on the system and heat is flowing into the system. The system does work on the surroundings when an ideal gas expands against a constant external pressure. All statements are true. All statements are false.

    Which of the following statements about pressure-volume work is true? The reversible process provides the maximum amount of work. Work done at constant-pressure is zero. When work is done on the system in an adiabatic process there is a decrease in the internal energy of the system. Changes in pressure-volume work must always be offset by changes in the heat of the system. A free expansion takes place against a constant external pressure of 1 bar.
