When 1 kg of ice at 0 degrees Celsius absorbs 80 kilocalories of heat, the ice undergoes
a) a change of state
b) a loss of energy
c) a rise in temperature
d) an increase in volulme
The heat of fusion of water is 80 kcal/kg. That means that 1 kg of ice will melt if it absorbs 80 kcal of heat. So what do you think you should have as an answer?
Here is a clue: That is the melting point (0 C) and heat of fusion (80 KCal/kg) of ice.
A more precise way of saying what happens is "a change in phase". The volume decreases. It does not increase. The temperature remains constant during melting
