In a thermally insulated container, 0.01 kg of ice at 273 K is mixed with 0.1 kg of water at 300 K

Q. In a thermally insulated container, 0.01 kg of ice at 273 K is mixed with 0.1 kg of water at 300 K. Neglecting the specific heat of the container, the change in the entropy of the system in J/K on attaining thermal equilibrium (rounded off to two decimal places) is (Specific heat of water is 4.2 kJ/kg-K and the latent heat of ice is 335 kJ/kg).
