If 1 mole of an ideal gas expands isothermally at `37^(@)C` from 15 litres to 25 litres, the maximum work obtained is `:`

One mole of an ideal gas expands isothermally at 300 K from 1 litre to 101 litres at constant pressure of 1 atmosphere. The work done during this change is (1 lit atrn = 24.2 cals)

1 mole of an ideal gas expands isothermally reversible from 2 litre to 4 litre and 3 moles of the same gas expands from 2 litre to x litre and doing same work, what is 'x'-

One mole of an ideal gas expanded freely and isothermally at 300 K from 5 litres to 10 litres. If DeltaE is 0 , then DeltaH is

Two mole of an ideal gas is expanded isothermally and reversibly from 1 litre to 10 litre at 300 K. The enthapy change (in kJ) for the process is
