What is density?

Back

Density is the mass of an object divided by its volume. It is a measure of how much matter is packed into a given space.

Front

How do you calculate density?

Back

Density = Mass / Volume

Front

What happens to objects with a density less than the liquid they are in?

Back

Objects with a density less than the liquid will float.

Front

What happens to objects with a density greater than the liquid they are in?

Back

Objects with a density greater than the liquid will sink.

What is the smallest unit of an element?

Back

The smallest unit of an element is called an atom.

Front

What is the difference between mass and weight?

Back

Mass describes the amount of matter in an object, while weight describes the force of gravity acting on that mass.

What units are commonly used to measure mass?

Back

Mass is commonly measured in grams (g) or kilograms (kg).

Front

What units are commonly used to measure volume?

Back

Volume is commonly measured in liters (L) or cubic centimeters (cm³).
