Final answer:
Yes, the statement is true. When sweat evaporates from the skin, it takes a significant amount of energy from the body, resulting in cooling.
Step-by-step explanation:
Yes, the statement is true. The evaporation of sweat is an important mechanism for temperature control in some warm-blooded animals. When sweat evaporates from the skin, it takes a significant amount of energy from the body, resulting in cooling. This helps regulate body temperature and prevent overheating. it requires a substantial amount of energy to transition from a liquid to a gas; this energy is taken from the body's heat, resulting in the cooling effect. This mechanism is crucial for maintaining homeostasis of body temperature, particularly during exercise or exposure to hot environments.
It's important to note that sweating is mostly an effective means of heat loss when the surrounding air is not saturated with moisture. In environments with high relative humidity, sweat does not evaporate as effectively, potentially leading to dangerously high internal body temperatures.
