The amount of energy needed to change 25 g of −30°C ice into 0°C liquid water is 8350 J.

Amount of heat required

The amount of heat required to change 25 g of −30°C ice into 0°C liquid water is calculated as follows;

Q = mLf

where;

  • m is mass of the ice
  • Lf is latent heat of fusion

Q =  25 x 334

Q =  8350

Thus, the amount of energy needed to change 25 g of −30°C ice into 0°C liquid water is 8350 J.
