4. none of these
The work done by a mass less piston in causing an expansion V (at constant temperature), when the opposing pressure, P is variable, is given by:
1. W=
2. W=0
3. W= -PV
4. none of these
The maximum work done in expanding 16 g of oxygen at 300 K and occupying a volume of 5 dm3 isothermally until the volume becomes 25 dm3 is:
1. -2.01 x 103 J
2. 2.81 x 103 J
3. 2.01 x 10-3 J
4. -2.01 x 10-6 J
During an adiabatic process:
1. pressure is maintained constant
2. gas is isothermally expanded
3. there is perfect heat insulation
4. the system changes heat with surroundings
The internal energy change when a system goes from state A to B is 40 kJ/mol. If the system goes from A to B by a reversible path and returns to state A by an irreversible path. What would be the change in internal energy?
1. 40 kJ
2. >40 kJ
3. <40 kJ
4. Zero
