Question 17 • Liberty - Physics A

Which is an example of conduction?

Answer
A
Soup is warmed in a microwave oven.
B
A hand is burned when touching a pot handle.
C
Air above an ocean warms up and rises.
D
A stone gets hot from sitting outside on a sunny day.

Explanation

Conduction transfers heat through direct contact. A hand touching a hot pot handle gains heat from the handle, so this is conduction. Soup warmed by a microwave and a stone warmed by sunlight involve radiation, while warm air rising is convection.
