A device that absorbs and draws heat from a hot object dispersing it into the surroundings is which one of the following?
Heat sink
Does heat rise or hot air rise?
Heat is the energy of the hot air. Therefore hot air rises
Why does cold water and air tend to sink?
cold air and water tend denser than hot air and water, so they sink
How does temperature affect air movement?
the hot air will rise and the cool air will sink
What can carry heat by convection?
Convection is when fluids (yes, air is considered a fluid) mix... Hot (less dense) molecules will rise as opposed to cold (more dense) molecules will sink.
When air loses its heat does it become less dense and sink?
When air loses its heat it actually becomes more dense and sinks which starts a convection current
Why does heat go from a hot place to a cooler place?
It loses heat to the surrounding air.
Why is the cooling unit of a freezer at the top?
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.

What does heat sink do?
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.
Why you use a 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.

How do you get super glue off of a sink?
super glue remover ANS 2 - Heat it with a good hairdryer or hot air gun, then remove with acetone.
Why does cold water and air tend to sink?
cold air and water tend denser than hot air and water, so they sink
How does temperature affect air movement?
the hot air will rise and the cool air will sink
What happens when you put hot air into the balloon?
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! :)
