371581 One mole of an ideal gas expands at a constant temperature of \(300\;K\) from an initial volume of 10 litre a to a final volume of 20 litres. The workdone in expanding the gas is

1 \(750\,joules\)
2 \(1728\,joules\)
3 \(1500\,joules\)
4 \(3456\,joules\)
PHXI12:THERMODYNAMICS

371582 10 moles of a ideal gas at constant temperature \(600\;K\) is compressed from \(100\;L\) to \(10\;L\). The work done in the process is

1 \(12 \times {10^4}\;J\)
2 \(-12 \times {10^4}\;J\)
3 \(11.4 \times {10^4}\;J\)
4 \(-11.4 \times {10^4}\;J\)
PHXI12:THERMODYNAMICS

371583 Heat is added to an ideal gas and the gas expands. In such a process the temperature

1 Must always increase
2 Will remain the same if the work done equals the heat added
3 Must always decrease
4 Will remain the same if change in internal energy equals the heat added
PHXI12:THERMODYNAMICS

371584 For an isothermal process,
I.
Pressure of a given mass of a gas varies inversely as its volume.
II.
During expansion of gas, work is done by the gas on environment.
III.
During compression heat is released
