Calculate the heat required to convert 250 g of ice into water at the same temperature (`0^(@)`C).

Text Solution

Verified by Experts

The correct Answer is:
20 kcal
1 g of ice requires 80 cal heat to get converted to water at `0^(@)`C. 250 g of ice requires 20000 cal (20 kcal) of heat to get converted to water.
