Question

Which property of water is demonstrated when we sweat?

1) high heat capacity
2) high heat of vaporization
3) polar solvent properties
4) reactivity
5) cushioning

Answer 1

When we sweat, the high heat of vaporization of water allows for temperature regulation by absorbing body heat and evaporating, cooling the body. The correct option is 2.

Step-by-step explanation:

The property of water that is demonstrated when we sweat is its high heat of vaporization. This refers to the considerable amount of energy required to change one gram of a liquid substance to a gas.

When we sweat, heat is absorbed by the sweat (which is primarily water) from our bodies; as the sweat evaporates, it takes this heat with it, resulting in the cooling of our bodies.

This process is essential in regulating body temperature and is made possible by the high heat of vaporization of water. The correct option is 2.
