А piece of ice having the mass of 0.2kg and initial temperature of 0°C is in mersed in
a copper vessel of mass 0.3kg and Containing 0.5kg of water at 35°C
Calculate the final temperature when all the
ice has melted. Assumed no loss of heat energy
Specific heat capacity of water is 4.2kg/k
Specific heat of Copper is 0.4kj/k
Specific Latent heat of fussion of ice 335kj/kg​
