convection

Warm air/water always

Rises

What does convection occur in?

Air,gases,liquids

Why is the air by the ceiling warmest

Because warm air rises and is light.

How can a glass of water reach thermal equilibrium?

By stirring a glass of water until the glass is equally heated

Which is denser? Cold air or warm air?

Cold air

Explain the cycle of convection

Cold air sinks pushing warm air up. Warm air soon cools pushing what was once cold air and now is warm air up.

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

Vibrate faster and faster.

How might convection happen in a pot of boiling water?

Water that is heated rises and cold water sits at bottom waiting to be heated.

Can convection happen in water?

Yes

Does convection occur in air?

Yes

Does convection happen everywhere?

Yes it even occurs inside and out side.

Is convection useful.

Yes it provides us with cool bair
