Question

which of the following is an example of heat transfer through convection? hint: look for the motion of a fluid like water or air. warm air rises in a room, and cool air sinks light and heat waves travel from a lamp a lizard lays on a hot sidewalk

Explanation:

Convection is heat transfer through the motion of fluids (liquids or gases). Warm air rising and cool air sinking in a room is due to the density differences in air (a fluid) caused by temperature variations, which is an example of convection. Light and heat waves traveling from a lamp is radiation. A lizard laying on a hot sidewalk is conduction.

Answer:

warm air rises in a room, and cool air sinks
