How could you use melting and boiling point to identify a substance

You can identify a substance, by testing the melting and boiling point and find a known substance that has the same melting and boiling points as the one tested

If it has a high boiling point and melting point the substance is most likely to be a solid if these values are low it will be a liquid. If they are negative values it will be a gas.

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.
