Compared to the quantity of heat needed to raise 10. grams of liquid water 5°C, the heat needed to raise the temperature of 10. grams of ice 5°C is

specific heat of water is 4.186 kJ/kgC

specific heat of ice is 2.06 kJ/kgC

specific heat of steam is 2.1 kJ/kgK

heat of fusion of ice is 334 kJ/kg

First part: assuming the water is NOT close to boiling point is

4.186 kJ/kgC x 0.01 kg x 5C = 209 joules

Second part: assuming the ice is NOT close to melting point

2.06 kJ/kgC x 0.01 kg x 5C = 104 joules

LESS
