One mole of an ideal gas at `27^@C` 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 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 300K is expanded isothermally from an inital volume of 1 letre 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))

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))

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