Calculate the energy required to raise 29.2 g of aluminum from 27.2˚C to 41.5˚C. (Specific heat of aluminum = 0.89 J/g*K)

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.
