Density

Front

What is the formula for calculating density?

Back

Density = Mass / Volume

Front

If an object has a mass of 10g and a volume of 5cm³, what is its density?

Back

2 g/cm³

Front

What is the density of water in g/cm³?

Back

1 g/cm³

Front

What does it mean for a substance to be less dense than water?

Back

It means the substance will float on water.

Front

What happens to the density of a substance when its temperature increases?

Back

Generally, the density decreases as temperature increases due to expansion.

If an object has a density of 1.2 g/mL, will it float or sink in water?

Back

It will sink because it is denser than water.

Front

What is the relationship between mass, volume, and density?

Back

Density is the ratio of mass to volume.

Front

How does heating air affect its density?

Back

Heating air causes it to expand, decreasing its density.

Why do balloons filled with hot air rise?

Back

They rise because the hot air inside is less dense than the cooler air outside.
