it is heat gain!
Transpiration
The water evaporates into the air. This is called evaporation. Evaporation is caused by the heat of the sun. If it is cloudy or cold, the water is not likely to evaporate.

Latent Heat of Evaporation, or Evaporation Enthalpy. It is given in units of energy over unit of mass, i.e., KJ/Kg.
You can use a heat lamp to study the effects of temperature on water evaporation. Place a tank filled with water under the heat lamp and monitor the rate of evaporation at different distances and intensities of light. By measuring the water level at regular intervals, you can analyze how temperature affects evaporation rates. This experiment can also illustrate concepts like heat transfer and the water cycle.
heat loss
evaporation
A temperature change requires as gain or loss of heat energy.
Evaporation
NO Heat Loss , No Heat gain
Humans can lose heat through processes such as conduction, convection, radiation, and evaporation. However, humans cannot gain heat through evaporation because it is a cooling process where heat is transferred from the body to the surrounding environment.
Body heat is not primarily lost through evaporation. It is typically lost through radiation, conduction, and convection. Evaporation can contribute to heat loss, but it is not the main mechanism in the human body.

metabolic heat production (heat gain) radiated convection conduction evaporation
Wind
The primary mode of heat loss in humans is through radiation, where body heat is emitted in the form of infrared radiation. Other modes of heat loss include conduction, convection, and evaporation.
A physical change in matter caused by a loss or gain of heat is called a thermal change.
