What is mass?

Back

Mass is the amount of matter in an object, usually measured in grams (g) or kilograms (kg).

Front

What is volume?

Back

Volume is the amount of space an object occupies, typically measured in cubic centimeters (cm³) or liters (L).

Front

What is density?

Back

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

Front

Why do some objects float while others sink?

Back

Objects float if their density is less than the density of the fluid they are in; they sink if their density is greater.

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

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

Back

Density = 10g / 5cm³ = 2 g/cm³.

Front

What is the formula for the volume of a rectangular prism?

Back

Volume = Length × Width × Height.

Front

Calculate the volume of a box with dimensions 4cm, 5cm, and 3cm.

Back

Volume = 4cm × 5cm × 3cm = 60 cm³.

Front

What happens to the density of an object if you increase its mass but keep its volume the same?

Back

The density increases.
