Chemical Engineering - Heat Transfer - Discussion

In a cooling tower, water becomes cool primarily by **vaporization due to heat loss to air**.

As water evaporates, it takes away heat from the remaining water, resulting in a cooling effect. This process involves both sensible heat (the heat that raises the temperature) and latent heat (the heat absorbed during vaporization), but the key cooling mechanism is the vaporization of water.

We know that "Heat gained by the system=Heat lost by the system", here water is loosing its heat, means that gained by some other body, and only it is sensible heat because no phase change occur.
