Question

Calculate the amount of heat needed to melt 35.0 g of ice at 0 ºC.Express your answer in kilojoules

Answer 1

The amount of heat will be equal to Lm.

Where L is the latent heat of fusion and m is mass of the ice.

Latent heat of ice = 80cal/g.

So the amount of heat required here will be 35× 80cal

= 2,800 cal.

Answer 2

that would be 2,800 calories
