How much heat does your body lose when 2.8 g of sweat evaporates from your skin at 25°C (Assume that the sweat is only water.) Show all work.

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.
