Suppose you are given a sample of a homogeneous liquid what would you do to determine whether it is a solution or a pure substance

We can determine it by distillation. Heat the sample till it starts boiling and starts vaporizing and maintain the temperature till the solution is either completely turned into vapor meaning its pure or leaves a solute behind meaning its a solution.

Ans. : frostbite is when exposure to cold temperatures causes freezing to the skin or other tissues. it most commonly affects the hands, feet, and face. the longer areas are exposed to cold, typically the worse the frostbite. the water temperature used for rewarming a frostbitten part should be : (102 -105) f degrees.
