Detailed explanation-1: -Evaporation removes heat and can act as a cooling mechanism. For instance, many mammals can activate mechanisms like sweating and panting to increase evaporative cooling in response to high body temperature.

Detailed explanation-2: -That’s because cooling your body via sweating relies on a principle of physics called “heat of vaporization.” It takes energy to evaporate sweat off of your skin, and that energy is heat. As your excess body heat is used to convert beads of sweat into vapor, you start to cool down.

Detailed explanation-3: -The evaporation of sweat provides by far the greatest potential for heat loss and it represents the only means of heat loss when air temperature exceeds skin temperature.

Detailed explanation-4: -When an animal pants, it evaporates water from internal body structures. Panting expels hot air and brings in cool air. Many animals use this method to cool down including dogs, cats and pigs.

Detailed explanation-5: -There are different ways of thermoregulation. A lot of animals will evaporate water through sweat glands. Animals that are covered in fur have limited ability to sweat and need to use heavy panting to increase the evaporation through the tongue, mouth and lungs. Dogs, cats and pigs rely on panting for their regulation.
