Which of the following is one of the four primary routes of heat loss?

Explanation:
Heat leaves the body mainly by emission of infrared radiation. This mode is one of the four primary routes of heat loss. It doesn't require contact with another surface or a surrounding medium, so heat can radiate away to cooler objects or space. The rate depends on the temperature difference between the body and its surroundings, the surface area exposed, and the skin’s emissivity. The other routes involve different mechanisms: conduction needs direct contact to transfer heat, convection uses moving air or fluid to carry heat away, and evaporation relies on water (sweat) changing to vapor to remove heat.
