Question

7) The amount of heat required to convert 8 g of ice into water at 0 degreesC is____ calories​

Answer 1

Answer:

✯♦Let us see, how much quantity of heat is required.

♦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 raise the temperature of 5g of water from 0°C to 100°C = 5g × 1calorie/g/1°C rise of temperature× 100°C= 500 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.
