Question

water makes up approximately 60% of the human body and plays a vital role in regulating body temperature. which property of water makes it good at regulating temperature? water has a high capacity for heat. water exhibits strong cohesion. water is a good solvent. water has an unusual crystalline structure.

Explanation:

To determine the property of water that aids in temperature regulation, we analyze each option:

• "Water has a high capacity for heat" (specifically high specific heat capacity) means water can absorb or release a large amount of heat with little temperature change, which is key for regulating body temperature.
• "Water exhibits strong cohesion" relates to water molecules sticking together, not temperature regulation.
• "Water is a good solvent" refers to dissolving substances, not temperature.
• "Water has an unusual crystalline structure" (like ice) is about its solid - state structure, not temperature regulation.

So the correct option is the one about water's high heat - related capacity.

Answer:

A. Water has a high capacity for heat.
