Answer :
Final answer:
The human body dissipates heat through four primary mechanisms: conduction, convection, radiation, and evaporation. Each of these mechanisms works based on the principle that heat flows from a region of higher concentration to a region of lower concentration.
Explanation:
The human body dissipates heat through four primary mechanisms: conduction, convection, radiation, and evaporation.
Conduction involves the transfer of heat between two objects in direct contact, such as when an animal rests on a warm rock. Convection happens when currents of air pass over the skin, removing heat from the surface. Radiation refers to the emission of electromagnetic 'heat' waves, through which heat comes from the sun and radiates from dry skin. Lastly, evaporation, such as when a mammal sweats, is the process where heat is removed with liquid from a surface. Each of these mechanisms relies on the property of heat to flow from a higher concentration to a lower concentration.
