Question

CHEMISTRY: After an afternoon party, a small cooler full of ice is dumped onto the hot ground and melts. If the cooler contained 6.20 kg of ice and the temperature of the ground was 38.5°C, calculate the energy that is required to melt all the ice at 0°C. The heat of fusion for water is 80.0 cal/g.

er an afternoon party, a small cooler full of ice is dumped onto the hot ground and melts. If the cooler contained 6.20 kg of ice and the temperature of the ground was 38.5, calculate the energy that is required to melt all the ice at 0°C. The heat of fusion for water is 80.0 callg. Number cal

Explanation / Answer

Heat required to melt the ice = mass of ice x heat of fusion for water

= 6.21 kg x (80.0 cal/g)

= (6.21x103 g) x (80.0 cal/g)

= 4.97x105 cal
