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.

Convert the temperature of dry ice, –77 ∞c, into degrees fahrenheit and kelvin.
