Two coins each weighting 10 g are heated to 473 K and dropped into two identical vessels A and B each containing 500 g of water at 298 K. The coin dropped in vessel A is made up of aluminium and the coin dropped into vessel B is made up of silver. The rise in temperature of water in container.

In thermodynamics, a process is called reversible when

Which one of the following statements is false?

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

The enthalpy of vaporization of liquid is 30 kJ mol^-1 and entropy of  vaporization is 75 J/ mol/K. The boiling point of the liquid at 1 atm is
