One mole of an ideal gas at 300 K is expanded isothermally from 1 litre volume to 10 litre volume. `Delta U` for this process is (R = 2 cal `K^(-1)mol^(-1)`)

One mole of an ideal gas at 300 K is expanded isothermally from an initial volume of 1 litre to 10 litre. The DeltaU for this process is (R = 2 cal K^-1 mol^-1) .

One mole of an ideal gas at 300K is expanded isothermally from an inital volume of 1 litre to 10 litres. The DeltaE for this process is (R=2cal mol^(-1)K^(-1))

One mole of an ideal gas at 250 K is expanded isothermally from an initial volume of 5 litre to 10 litres. The Delta E for this process is (R = 2 cal. Mol^(-1)K^(-1))
