Density Tutoring Activity

Front

What is density?

Back

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

Front

How do you determine if an object will float or sink in a liquid?

Back

An object will float in a liquid if it is less dense than the liquid. It will sink if it is more dense.

Front

What is the relationship between density and buoyancy?

Back

Buoyancy is the ability of an object to float in a fluid. An object that is less dense than the fluid will experience a buoyant force that allows it to float.

Front

What happens to the density of a substance when it is heated?

Back

Generally, when a substance is heated, its density decreases because its volume increases.

Front

What is the density of water?

Back

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

Front

Why do ice cubes float in water?

Back

Ice cubes float in water because ice is less dense than liquid water.

Front

What is a common unit of measurement for density?

Back

Common units for density include grams per cubic centimeter (g/cm³) and kilograms per cubic meter (kg/m³).

Front

If a liquid has a density of 1.5 g/cm³, will it float on water?

Back

No, it will sink because it is denser than water (1 g/cm³).

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

What is an example of a dense liquid?

Back

Syrup is an example of a dense liquid.
