What happens to particles when temperature increases?

Back

They get further apart.

Front

Why do some substances float on water?

Back

They are less dense than water.

Front

What happens to the density of an object when it is heated?

Back

Density decreases.

Front

What is the formula for calculating density?

Density = Mass / Volume.

Front

If an object has a mass of 10g and a volume of 2cm³, what is its density?

Back

5 g/cm³.

Front

What happens to the density of an object when it is cooled?

Back

Density increases.

Front

What is the relationship between temperature and particle movement?

Back

As temperature increases, particle movement increases.

Front

What is density?

Back

Density is the mass of an object divided by its volume.

Front

What is the unit of density in the metric system?

Back

g/cm³ (grams per cubic centimeter).

Front

Why do hot air balloons rise?

Back

The air inside the balloon is less dense than the cooler air outside.
