explain the method of convection in a hot air balloon need correct explanation
Answers
Answer:Convection is the transfer of heat energy via the vertical movement of the air. ... A hot air balloon rises because warmer air is less dense than cool air. Since the balloon is less dense than the air around it, it becomes positively buoyant.
Explanation:
Answer:
EXPLANATION
The air expands and some of the air will be pushed out of the balloon. This reduces the mass of air in the balloon. Therefore the balloon will be less dense tahn the cool air outside.The same thing happen if we heat the air without the balloon there. The hot air will become less dense than the the surrounding cool air and will float up over it. As the hot air rises, it leaves a gap behind which will be filled by fresh cooled air. This will get heated and rise up, dragging in more cool air .
