Heat transfer through liquids, air, or a solid rock is known as

Convection

Cold air sinks because

It is denser.

Warm air rises because

It is light and pushed up by cold air

What is thermal equilibrium?

It is when a a liquid is equally heated.

Cold air/water always

Sinks

How do you think convection applys to air conditioners being on ceilings?

So the cold air flows to the room sinking to the ground creating a convection current

Convection is

The cycle of cool air and warm air rising and sinking

A convection current is

The flow of hot and cold regions through a fluid.

When water particles heat up they
