In an experiment, 1 kg of water, initially at 283 K is heated to 363 K via two processes. In process I, water is brought into contact with a heat reservoir at 363 K. In process II, water is first brought into contact with a heat reservoir at 323 K and then in contact with another reservoir at 363 K . Assume that the specific heat capacity of water, C is independent of temperature. Choose the correct options from the

Options
