Yes, hot air rises when heated because it becomes less dense than the surrounding cooler air. As the hot air gives off heat and cools down, it becomes denser and eventually sinks back down. This movement is part of the natural convection process in which heat is transferred through liquids and gases.
Hot air moving up is an example of convection, a heat transfer process where hot fluids rise and cool fluids sink. This process occurs due to the differences in density between the hot and cold fluids.
Heat sink
Hot water cools down by transferring heat energy to its surroundings. This usually occurs through convection and conduction, where the hot water loses heat to the cooler air or container it is in contact with. As the hot water cools, its molecules slow down and its temperature decreases until it reaches equilibrium with its environment.
One method of heat transfer that removes heat from hot liquids is convection. This occurs as the hot liquid loses heat to its surrounding environment as cooler particles come into contact with the hot liquid and carry the heat away.
In the process of heat transfer, hot air moves to cold air.
It loses heat to the surrounding air.
This is because, hot air rises and cold air sinks. When the air near the cooling unit loses heat, it will sink to the bottom whereas the hotter air at the bottom will rise to the top. This is due to the density difference between them, since hot air has a lower density than cold air, hot air will rise. When they rise, they will be cooled by the cooling unit too. And then sink to the bottom again. This cycle will then repeat itself until the air is of a constant temperature.
Yes, when air loses heat, it becomes denser because the air molecules contract and move closer together. As a result, denser cool air sinks while warmer, less dense air rises. This movement of air based on density differences is a key factor in atmospheric circulation and weather patterns.

It helps conduct heat away from the object on which it is placed. Without the heat sink, a computer CPU would get too hot to function.
Heat sink
A heat sink increases the surface area of a hot item and increases the ability of the item to cool or be cooled.

super glue remover ANS 2 - Heat it with a good hairdryer or hot air gun, then remove with acetone.
In hot air, particles are moving faster due to the increase in heat. This makes hot air lighter than cold air so the hot air will rise. When you put hot air into a balloon, the hot air will try and rise to the top. This allows the balloon to float in the air. Eventually the air will cool and sink back down which is why it's important to continuously pump hot air into the balloon to keep it up. Hope this helps! :)
If it is cooled its gets extremely cold from the helium,and when the heat is in the balloon it keeps it warm when its in the helium
