Which of the following methods does NOT transfer heat?

Insulation is the method that does not transfer heat. Instead of transferring heat, its primary purpose is to resist or prevent the transfer of heat between two areas. Insulation materials are designed to hold heat in or keep it out, thereby maintaining the desired temperature of an environment. They act as barriers that slow down the movement of thermal energy.

In contrast, conduction, convection, and radiation are all methods of heat transfer. Conduction involves the direct transfer of heat through materials that are in physical contact, while convection refers to the movement of heat through fluids (liquids and gases) by the circulation or movement of the fluid itself. Radiation is the transfer of heat through electromagnetic waves, allowing energy to travel through a vacuum without the need for a medium. Understanding how insulation works in relation to these heat transfer methods is crucial for efficient temperature control in air conditioning systems and energy conservation.
