On a summer day, Thomas is standing in his driveway waiting for his mother . Energy from the Sun is making Thomas feel hot. This energy is being transmitted by three different methods. Which of the following is an example of convection?

Question

A. Energy streaming through space toward Thomas.
B. Heat being transferred from air particles to the asphalt.
C. Heat moving through Thomas’s clothes to warm his skin.
D. Warm air rising from just above the asphalt to reach the level of Thomas’s face

Answer 1

The correct answer is:

D. Warm air rising from just above the asphalt to reach the level of Thomas’s face.

Convection involves the transfer of heat through the movement of fluids (such as air or water), where warmer, less dense areas rise and cooler, denser areas sink. In this case, the warm air rising is an example of convection.
