Density Practice

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) or grams per milliliter (g/ml).

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What is the density of water?

Back

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

Front

What happens to the density of an object if its mass increases but its volume remains the same?

Back

The density increases.

Front

What happens to the density of an object if its volume increases but its mass remains the same?

Back

The density decreases.

Front

Why does ice float on water?

Back

Ice floats because it is less dense than liquid water.

Front

If an object has a density of 0.5 g/cm³, will it float or sink in water?

Back

It will float because it is less dense than water.

Front

What is the density of a liquid with a mass of 27g and a volume of 30ml?

Back

0.9 g/ml.

Front

If you cut an object in half, what happens to its density?

Back

The density remains the same.

Front

What is the density of an eraser with a mass of 4g and a volume of 2cm³?

Back

2 g/cm³.
