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.

Front

How do you calculate Density?

Back

Density is calculated using the formula: Density = Mass (g) / Volume (mL or cm³).

Front

What units are used to measure Density?

Back

Density is commonly measured in grams per milliliter (g/mL) or grams per cubic centimeter (g/cm³).

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

Back

If the mass increases and the volume stays the same, the density of the object increases.

Front

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

Back

If the volume increases and the mass stays the same, the density of the object decreases.

Why do some objects float in water while others sink?

Back

Objects float in water if their density is less than the density of water (1 g/mL). They sink if their density is greater than that of water.

Front

What is the density of water?

Back

The density of water is approximately 1 g/mL at room temperature.

Front

If an object has a density of 9 g/mL, will it float or sink in water?

Back

An object with a density of 9 g/mL will sink in water because it is denser than water.

Front

What is the relationship between density and layering of liquids?

Back

Liquids with different densities will form layers, with the denser liquid at the bottom and the less dense liquid on top.

What is the formula for calculating the volume of an irregularly shaped object using water displacement?

Back

The volume of an irregularly shaped object can be calculated by measuring the change in water level in a graduated cylinder after the object is submerged.
