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

What is the formula for calculating Density?

Back

Density = Mass / Volume

Front

What units are commonly used to measure Mass?

Back

Grams (g) and kilograms (kg) are commonly used to measure mass.

Front

What units are commonly used to measure Volume?

Back

Milliliters (ml) and cubic centimeters (cm³) are commonly used to measure volume.

Front

How does temperature affect the density of a substance?

Back

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

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

What tool is used to measure mass accurately?

Back

A triple beam balance is used to measure mass accurately.

Front

If an object has a mass of 30g and a volume of 10cm³, what is its density?

Back

Density = 30g / 10cm³ = 3 g/cm³.

Front

What happens to an object with a density greater than water?

Back

An object with a density greater than water (1 g/cm³) will sink.

Front

What happens to an object with a density less than water?

Back

An object with a density less than water (1 g/cm³) will float.
