Density

Front

What is density?

Back

Density is a measure of how much mass is contained in a given volume. It is calculated using the formula: Density = Mass/Volume.

Front

What is the formula to calculate density?

Back

Density = Mass / Volume.

Front

If an object has a density less than 1 g/mL, what will it do in water?

Back

It will float.

Front

What happens to an object with a density greater than 1 g/mL when placed in water?

Back

It will sink.

Front

What are the common units for measuring density?

Back

g/mL (grams per milliliter) and kg/m³ (kilograms per cubic meter).

Front

What two measurements are needed to calculate density?

Back

Mass and Volume.

Front

How does temperature affect the density of a substance?

Back

Generally, as temperature increases, density decreases because substances expand.

Front

What is the density of water?

Back

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

Front

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

Back

Density is directly proportional to mass and inversely proportional to volume.

Front

What is an example of a substance that floats in water?

Back

A ping pong ball, because its density is less than that of water.
