Question

Liquid water of mass 10 kg and temperature 20c is mixed with 2 kg of ice at 5c till equilibrium is reached at 1 atm pressure. Find the entropy change of the system. Given: c p of water = 4.18 kj/kg k, c p of ice = 2.09 kj/kg k and latent heat of fusion of ice = 334 kj/kg.

Answer 1

Answer:

Since ice is saturated, so it will absorb heat in the form of latent heat to convert into water.

So final temp of mixture is 0°c and mixture is saturated water.

Answer 2

Answer:

Liquid water of mass 10 kg and tempera ture 20°C is mixed with 2 kg of ice at 5°C till equilibrium is reached at 1 atm pressure. Find the entropy change of the system. Given: of water = 4.18 kJ/kg K, c, of ice = 2.09 kJ/kg K and latent heat of fusion of ice = 334 kJ/kg.
