How much heat must be supplied to a 5 g chunk of ice initially at a temperature of -30^oC in order to convert the ice to steam at 125^oC? (Hint - you have to calculate five different Q values).

Required information:

Ice specific heat: 0.5 cal/g ^oC

Water specific heat: 1.0 cal/g ^oC

Steam specific heat: 0.48 cal/g ^oC

Latent heat of fusion for water, Lf = 80 cal/g

Latent heat of vaporization of water, Lv = 540 cal/g
