a) How many joules are required to change 0.650 kg of solid lead at 22.0 oC to a liquid at 1300.0 oC? (Assume the specific heats of both solid and molten lead to be the same.)
b) If the energy that goes into evaporating one kilogram of water from Lake Michigan at 10.0 oC were used instead to raise that amount of water above the surface of the lake, how high (in m) would it be lifted?
