question
which of the following statements about waters ability to help us maintain homeostasis are true?
select all that apply
it takes a lot of heat energy to change the temperature of water.
when heated, liquid water is easily converted into water vapor.
when water in sweat evaporates, it removes heat from our body.
water molecules exhibit hydrogen bonding and are hard to separate from each other.

Explanation:

Water has a high specific - heat capacity, meaning it takes a lot of heat energy to change its temperature, which helps in maintaining body temperature homeostasis. When water in sweat evaporates, it is an endothermic process that removes heat from the body, aiding in cooling. Water molecules have hydrogen bonding which makes them hard to separate and contributes to its unique thermal properties. Liquid water is not easily converted into water vapor due to hydrogen bonding; it requires a significant amount of energy for evaporation.

Answer:

It takes a lot of heat energy to change the temperature of water.
When water in sweat evaporates, it removes heat from our body.
Water molecules exhibit hydrogen bonding and are hard to separate from each other.
