Summary Introduction

To review:

The reason for the cooling effect of evaporation.

Introduction:

The four mechanisms for transfer of heat are conduction, convection, evaporation, and radiation. Radiation accounts for most of the transfer of heat whereas evaporation accounts for about 10% to 25% of the heat transfer between a body and its surroundings, depending upon the conditions. These mechanisms ensure that the temperature of the body does not alter from its normal range, in order to maintain the homeostasis.
