Expert Solution

Solution:

Given,

mass of ice

Latent heat if fusion of ice

specific heat of ice

The ice is at a initial temperature of

The final temperature is

So, the change in temperature

The heat energy supplied to the ice will be used in increasing the temperature and for liquifying the ice.

Heat energy for temperature increse from to is

Heat energy for liquifying ice at is

So, the heat energy Q is given by,.
