Is cooling hot water an exothermic process or an endothermic process?

Because we must add heat, boiling water is a process that chemists callendothermic. Clearly, if some processes require heat, others must give off heat when they take place. These are known as exothermic.

Hydrogen is the most abundant element on the periodic table..hope it .

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.
