What happens to the density of a substance when it is heated?

Back

When a substance is heated, its density usually decreases because the particles move apart.

How does a lava lamp demonstrate convection?

Back

In a lava lamp, the colored liquid heats up, becomes less dense, and rises, while cooler liquid sinks, creating a convection current.

What is an example of conduction in everyday life?

Back

An example of conduction is when a metal spoon gets hot after being placed in a hot pot of soup.

Front

What is an example of radiation in everyday life?

Back

An example of radiation is feeling warm from the sun on your skin.

Front

What is an example of convection in everyday life?

Back

An example of convection is warm air rising and cool air sinking in a room.
