Question

water evaporating from your skin is an example of
select one:
○ a. passive heat absorbtion.
○ b. heat energy.
○ c. latent heat transfer.
○ d. senible heat.

Explanation:

• Option a: Passive heat absorption is not the right term for evaporation - related heat transfer. Evaporation involves a phase change, not just passive absorption.
• Option b: Heat energy is a general term. The process of water evaporating from skin is a specific type of heat transfer, not just heat energy itself.
• Option c: Latent heat transfer occurs during phase changes (like evaporation, where liquid water becomes water vapor) without a change in temperature. When water evaporates from the skin, it absorbs heat (latent heat of vaporization) from the skin, cooling it. This is latent heat transfer.
• Option d: Sensible heat is related to temperature changes (e.g., heating a liquid to raise its temperature), not phase changes. Evaporation is a phase change, so this is incorrect.

Answer:

c. latent heat transfer.
