1. The latent heat of vaporization of ethanol is 8.46 x 105 J/kg. How many kg of ethanol can be vaporized by 4.52 x 104 J of heat?

2. 1.82 x 104 J of heat flow into 0.0442 kg of ice at 0C, causing the ice to melt and then the temperature of the melted ice to increase. What is the final temperature of the liquid water? (The specific heat of liquid water is 4186 J/kgC; the latent heat of fusion of water is 3.33 x 105 J/kg)

3. A certain mass of lead (Pb) at 200C were added to 0.500 kg of water at 20C. Their final, equilibrium temperature was 25C. What mass of lead was added to the water?

(Specific heats: water = 4186 J/kgC, lead = 128 J/kgC)
