Expert Solution
Step 1
Concept:
Formula for heat transfer is
where,
Q=heat transfer,
m= mass of the substance,
= change in temperature.
c =Specific heat
To change the phase of a sample of mass m the Heat Q required is,
where
Q =the amount of heat absorbed
M= mass
Lf= latent heat of fusion
Lv= latent heat of vaporization
Thus to change the temperature of ice the heat required will be
