Density

Front

What is density?

Back

Density is a measure of how much mass is contained in a given volume. It is calculated using the formula: density = mass / volume.

Why does ice float on water?

Back

Ice floats on water because solid water (ice) is less dense than liquid water.

Front

What is the formula for calculating density?

Back

The formula for density is: density = mass / volume.

Front

What tool is used to measure mass?

Back

The tool used to measure mass is a triple beam balance.

Front

How do you arrange liquids from most dense to least dense?

Back

To arrange liquids from most dense to least dense, you compare their densities. For example, if you have liquids with densities of 4, 3, 2, and 1, the order is 4, 3, 2, 1.

Front

What density will an object have to float on water?

Back

An object must have a density less than 1 g/cm³ to float on water.

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 water as it freezes?

Back

As water freezes, its density decreases, which is why ice floats.

Front

What is the relationship between mass and volume in density?

Back

Density is directly proportional to mass and inversely proportional to volume. If mass increases while volume remains constant, density increases.

Front

How can you determine if an object will sink or float?

Back

An object will sink if its density is greater than the density of the fluid it is placed in; it will float if its density is less.
