Heat of Fusion and Heat of Vaporization Worksheet
Q = mH,
Q = mH.
Q = mH,
Q = heat energy (3)
m = mass (g)
H = heat of fusion (3/g)
Hy = heat of vaporization (3/g)
H. = heat of condensation (J/g)
1. Calculate the heat energy required, in joules, to melt 5.00 x 10' grams of ice which is
at 0.0°C. The heat of fusion of ice is 333.6 J/g.
ice (0.0°C) - water (0.0°C)
2. Calculate the heat released when 2.00 x 10 grams of steam at 100°C condenses to
form water at 100°C. The heat of condensation of steam is 2258 J/g.
steam (100°C) - water (100°C)
3. Liquid ammonia is a common refrigerant because it absorbs so much heat energy
when it turns from the liquid to a gas. The heat of vaporization of liquid ammonia is
1374 J/g. Calculate the heat needed to turn 454 grams of liquid ammonia at its
boiling point to ammonia gas at the same temperature.
