Density

Front

What is density?

Back

Density is defined as the mass of an object divided by its volume. It is a measure of how much mass is contained in a given volume.

Front

What is the formula for calculating density?

Back

The formula for calculating density is Density = Mass/Volume.

Front

What units are commonly used to express density?

Back

Common units for density include grams per cubic centimeter (g/cm³) and kilograms per cubic meter (kg/m³).

Front

How do you calculate the volume of an object?

Back

Volume can be calculated using the formula Volume = Mass/Density.

Front

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

Back

Mass, volume, and density are related through the formula Density = Mass/Volume. If you know any two of these values, you can calculate the third.

What is the significance of density in identifying substances?

Back

Density can be used to identify substances because each substance has a unique density at a given temperature and pressure.

Front

How does temperature affect the density of a substance?

Back

Generally, as temperature increases, the density of a substance decreases because the volume tends to increase.

Front

What is the principle of buoyancy in relation to density?

Back

The principle of buoyancy states that an object will float in a fluid if its density is less than the density of the fluid.

Front

How can you determine if an object will sink or float in water?

Back

An object will sink in water if its density is greater than 1 g/cm³ and will float if its density is less than 1 g/cm³.

Front

What is the density of water at 4°C?

Back

The density of water at 4°C is approximately 1 g/cm³.
