A. The heat is needed to melt 100.0 grams of ice that is already at 0°C is +33,400 J.
Specific heat capacity is the quantity of heat needed to raise the temperature per unit mass.
The heat is needed to melt 100.0 grams of ice that is already at 0°C is calculated as follows;
Q = mL
where;
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.
