Mass, volume and 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 the density of an object?

Back

Density = Mass / Volume.

Front

What is the formula for volume of a rectangular prism?

Back

Volume = Length × Width × Height.

Front

What is the unit of mass in the metric system?

Back

The unit of mass in the metric system is the gram (g).

Front

What is the relationship between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

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

Back

The density increases.

Front

What is the volume of an object with a mass of 50g and a density of 2g/cm³?

Back

Volume = Mass / Density = 50g / 2g/cm³ = 25 cm³.

Front

What is the principle of buoyancy?

Back

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

Front

What is the density of water?

Back

The density of water is approximately 1g/cm³.

Front

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

Back

If the object's density is greater than 1g/cm³, it will sink; if it is less, it will float.
