Question

Calculate the amount of heat required 5g of ice of 0°C into water at 0°C​

Answer 1

Answer:

Heat required to melt 5g of ice at 0°C to water at 0°C = 5g × 80 calorie per gram= 400 calorie. Heat required to convert water at 100°C to steam at 100°C = 5g× 540calorie/g = 2700calorie. Therefore total heat required = 400 calorie+500 calorie + 2700 calorie= 3600 calorie.

Answer 2

Answer:

Heat required to melt 5g of ice at 0°C to water at 0°C = 5g × 80 calorie per gram= 400 calorie. Heat required to convert water at 100°C to steam at 100°C = 5g× 540calorie/g = 2700calorie. Therefore total heat required = 400 calorie+500 calorie + 2700 calorie= 3600 calorie
