The cold feeling that you experience after leaving a swimming pool on a hot, dry, summer day represents heat transfer by:

The correct answer is B. Convection.

When you leave a swimming pool on a hot, dry, summer day, you feel cold because your body heat is transferred to the air around you by convection. Convection is the transfer of heat by the movement of fluids. In this case, the fluid is the air. As your body heat warms the air around you, the warm air rises and is replaced by cooler air. This process continues until your body temperature reaches the same temperature as the air around you.

The other options are incorrect for the following reasons:

• Conduction is the transfer of heat between two objects that are in direct contact with each other. In this case, your body is not in direct contact with the air, so conduction is not the mechanism of heat transfer.
• Radiation is the transfer of heat through electromagnetic waves. In this case, the sun is the source of the electromagnetic waves, and your body is not absorbing any of these waves. Therefore, radiation is not the mechanism of heat transfer.
• Latent heat is the heat that is absorbed or released during a change of state, such as when water changes from a liquid to a gas. In this case, your body is not changing state, so latent heat is not the mechanism of heat transfer.
