Front

What is the formula to calculate mass using density and volume?

Back

Mass = Density × Volume

Front

What is the definition of density?

Back

Density is the mass of a substance that fills one unit of volume.

Front

What is matter?

Back

Matter is anything that has mass and takes up space.

Front

How does the density of air change when it gets hotter?

Back

The density of air decreases as it gets hotter.

Front

Which state of matter generally has the highest density?

Back

Solid has the highest density.

Front

What is the unit of density commonly used in liquids?

Back

g/mL (grams per milliliter) is commonly used for liquids.

Front

If a liquid has a density of 1 g/mL, what is its mass if the volume is 50 mL?

Back

Mass = 1 g/mL × 50 mL = 50 grams.

Front

What happens to the density of a substance if its mass increases while its volume remains constant?

Back

The density increases.

Front

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

Back

Density is the ratio of mass to volume (Density = Mass/Volume).

Front

What is the density of water at 4°C?

Back

The density of water at 4°C is approximately 1 g/mL.
