Which best describes the process of heat transfer that allows a hot air balloon to fly?
A.
Convection, because the air inside the balloon is heated and as the hot air rises, so does the balloon.
B.
Conduction, because the air inside the balloon is cooled when it is enclosed, causing the balloon to rise.
C.
Convection, because the air inside the balloon is condensed and as the cool air circulates, the balloon rises.
D.
Conduction, because the air inside the balloon is warmed, and when it comes in contact with the sides of the balloon, the balloon rises.
