Question

Your body produces sweat when you are hot.

What temperature is the sweat when it is first
produced? explain your answer.​

Answer 1

That's because cooling your body via sweating relies on a principle of physics called "heat of vaporization." It takes energy to evaporate sweat off of your skin, and that energy is heat. As your excess body heat is used to convert beads of sweat into vapor, you start to cool down.
