Density

Front

What is density?

Back

Density is the mass of an object divided by its volume, typically expressed in grams per cubic centimeter (g/cm³).

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

Does the density of an object change with its size?

Back

No, the density of an object remains the same regardless of its size, as long as its mass and volume change proportionally.

Front

What happens to the density of a substance when it is heated?

Back

Generally, the density decreases when a substance is heated because its volume increases.

Front

What is the relationship between density and buoyancy?

Back

An object will float in a fluid if its density is less than the density of the fluid.

Front

If two objects have the same volume but different masses, which one has a higher density?

Back

The object with the greater mass has a higher density.

Front

What is the density of water?

Back

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

Front

How does temperature affect the density of liquids?

Back

As temperature increases, most liquids expand, leading to a decrease in density.

Front

What is the formula for finding the volume of a cube?

Back

Volume = side length × side length × side length (V = s³).

Front

If a cube has a mass of 64 g and a volume of 8 cm³, what is its density?

Back

Density = Mass / Volume = 64 g / 8 cm³ = 8 g/cm³.
