Question 193

Which statement about convection is not correct?

A

It is the primary method of thermal energy transfer in solid metals.

B

It occurs when a fluid expands upon heating, decreasing its density and causing it to rise.

C

It plays a significant role in meteorological processes like wind and sea breezes.

D

It requires a medium and therefore cannot occur in a vacuum.
