Question 1

A 2294-kg sample of water at 0° C is cooled to and freezes in the process. How much heat is liberated? For water LF = 334,000 J/kg and LV = 2.256 × 106 J/kg. The specific heat of ice is 2050 J/kg ∙ K.
◦ 1,110,000 kJ
◦ 334,000 kJ
◦ 597,000 kJ
◦ 935,000 kJ

Question 2

Heat is added to a 3.0 kg piece of ice at a rate of How long will it take for the ice at 0.0° C to melt? For water LF = 334,000 J/kg and LV = 2.246 × 106 J/kg.
