Question

1. which property of water involve sweat during exercise *

○ ability to moderate temperature
○ universal solvent
○ expand upon freezing

Explanation:

Sweating during exercise uses the property of water's ability to moderate temperature (specifically, high heat of vaporization). When sweat evaporates, it absorbs heat from the body, cooling it. "Universal solvent" relates to dissolving substances, and "expand upon freezing" is about water's solid - liquid density change, neither related to sweating's cooling effect.

Answer:

A. Ability to moderate temperature
