Final answer:
Water conversion from liquid to gas occurs through evaporation, a form of body heat loss.the correct answer is b. Evaporation
Step-by-step explanation:
The conversion of water from a liquid state into a gaseous state happens with evaporation, which is a form of body heat loss. Evaporation occurs when liquid molecules escape into the gas phase, becoming water vapor. This process is commonly observed when sweat evaporates from the surface of the skin, resulting in a cooling effect.
