Heat is defined by how fast molecules are moving. Fast moving molecules will have a higher temperature than slow moving molecules.
The kinetic energy of the hot air is transferred to the cold air, which means the cold air becomes a little warmer, and the hot air becomes cooler.

Hot air. That's what makes it float.

If there is warm air in the balloon, cooler air makes the balloon rise and if there is cold air in the balloon warmer air makes the balloon fall.
The answer to your question is yes. Hot air makes you feel warm and comfortable. In addition, hot air makes your brain nerves relaxing. So, this way you feel sleepy.Now, cold air makes you very cold and uncomfortable. That is why you run when it is cold outside. For example: When you play in the snow, you feel very cold but after you start to play you are warm. That is the way it works.Good luck with answering!!!
Hot air is lighter than cold air, so cold air sinks and hot air rises; that makes the hot air balloon rise (if the air around the hot air balloon is heated as well, it won't rise, or sink if in the air).
if you mean how the hot air in a hot air balloon makes it rise, its because hot air is less dense than cold air. when cold and hot air meet the cold air sinks thus making hot air left to rise.so when you put hot air in a balloon the air would rise. hope this helps.
You have to get it recharged. you have no freeon left which makes the cold air
Hot air. Because it always rises above cold

Hot air is actually less dense than cold air. The molecules in hot air are further apart from one another.
