1. A cylinder fitted with a piston contains 3 moles of helium at 400K and 1.00 atm. Pressure. The pressure is increased reversibly to 5atm. Determine w, q and ?E for this process. (R= 8.314 J/mol/K)

2. To what pressure must a given volume of nitrogen originally at 100oC and 1 atm. Pressure, be adiabatically compressed in order to raise its temperature to 400oC.

3. Calculate the work that can be done by a mass of 400 g, falling a distance of 2.75 meters. How much heat could be produced if this mass was allowed to fall freely this distance? What would be the value of ?E mechanical reservoir in the first case and ?E thermal reservoir in the second?

4. A sample of an ideal monatomic gas at 1 atm pressure and 25oCexpands reversibly and isothermally from 1 liter to 4 liters. Determine the work done during the expansion.

5. A cylinder containing 1 mole of liquid water at 100oC is heated until the liquid is converted to vapour. The cylinder is fitted with a piston which just resists a pressure of 1 atm. How much work is done by the expanding gas? If the heat of vaporization of water is 40670 joules, what is the change in internal energy?

6. At 0oC the volume of 2 moles of an ideal monatomic gas is 22.415liters. The gas is expanded until its pressure is 1atm. By a reversible adiabatic process. Determine the final volume, temperature and work done.
