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 (D) = Mass (m) / Volume (V).

Front

What is the formula to calculate density?

Back

The formula to calculate density is D = m / V, where D is density, m is mass, and V is volume.

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

Back

Density = 10g / 5cm³ = 2g/cm³.

Front

What units are commonly used for density?

Back

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

Front

How does temperature affect the density of a substance?

Back

Generally, as temperature increases, the density of a substance decreases because the substance expands.

What is the density of water?

Back

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

Front

What happens to the density of an object if its mass increases while its volume remains constant?

Back

If the mass increases while the volume remains constant, the density of the object increases.

Front

What is buoyancy?

Back

Buoyancy is the ability of an object to float in a fluid, which is determined by the density of the object compared to the density of the fluid.

Front

If an object is less dense than the fluid it is in, what will happen?

Back

If an object is less dense than the fluid, it will float.

Front

If an object is more dense than the fluid it is in, what will happen?

Back

If an object is more dense than the fluid, it will sink.
