Final answer:
The hot air balloon rising is an example of convection, which is the transfer of heat energy through the movement of a fluid. The hot air inside the balloon is less dense than the cooler air outside, causing it to rise and create a convection current.
Explanation:
The hot air balloon rising is an example of convection. Convection is the transfer of heat energy through the movement of a fluid, such as air or water. In this case, the hot air inside the balloon rises because it is less dense than the cooler air outside. This creates a convection current that causes the balloon to float.
