Sagot :

A. The heat is needed to melt 100.0 grams of ice that is already at 0°C is +33,400 J.

What is Specific heat capacity?

Specific heat capacity is the quantity of heat needed to raise the temperature per unit mass.

Heat needed to melt the cube of ice

The heat is needed to melt 100.0 grams of ice that is already at 0°C is calculated as follows;

Q = mL

where;

  • m is mass of the ice
  • L is latent heat of fusion of ice = 334 J/g

Q = 100 x 334

Q = 33,400 J

Thus, the heat is needed to melt 100.0 grams of ice that is already at 0°C is +33,400 J.
