Getting a chill when standing near a cold wall is an example of what type of cooling?

The experience of feeling a chill when standing near a cold wall is primarily an example of conduction. In this context, conduction refers to the transfer of heat through a material without the movement of the material itself. When you stand near a cold wall, your body loses heat to the colder surface, resulting in a sensation of chill.

Convection involves the transfer of heat through the movement of fluids or air; for instance, warm air rising and being replaced by cooler air. This doesn't apply in your scenario, as standing next to a wall is not dependent on moving air currents.

Radiation, although it involves heat transfer, does so without the need for a medium, allowing heat to be emitted in the form of electromagnetic waves; however, it is less relevant in this instance since the sensation of chill is due more to direct contact with the cold wall than to heat loss via radiation.

While evaporation is a process where liquid turns into vapor and takes away heat, it is not what causes you to feel cold next to the wall. Instead, the sensation comes directly from conduction. Thus, the correct reasoning aligns with understanding that the transfer of heat through direct contact is what causes the chill in this scenario.
