What is density?

Density is a physical property of matter that measures the relationship between an object's mass and volume. It is calculated by dividing the mass of an object by its volume, and it indicates how tightly packed the particles of a substance are. Objects with higher density have more mass per unit volume compared to objects with lower density.

How is density calculated?

Density is calculated by dividing the mass of an object by its volume. The formula for density is: Density = Mass / Volume. This measurement is commonly expressed in units such as grams per cubic centimeter (g/cm³) or kilograms per liter (kg/L). By knowing the mass and volume of an object, you can easily calculate its density.

What is the unit of density?

The unit of density is typically expressed in kilograms per cubic meter (kg/m^3) in the International System of Units (SI).

What does it mean if an object's density is less than 1 g/cm³?

If an object's density is less than 1 g/cm³, it means that the object is less dense than water. This indicates that the object will float on water, as water has a density of 1 g/cm³. Objects with a density less than 1 g/cm³ are typically less compact or lighter than water, causing them to displace less water and therefore float.

What does it mean if an object's density is greater than 1 g/cm³?

If an object's density is greater than 1 g/cm³, it means that the object is more dense than water. In other words, if you were to compare the weight of a volume of the object to an equal volume of water, the object would weigh more. This indicates that the particles of the object are packed closer together, leading to a higher density measurement.

How does temperature affect density?

As temperature increases, the density of most substances decreases. This is because as substances are heated, their particles gain energy and move further apart, leading to a decrease in density. Conversely, as temperature decreases, the density of most substances increases as particles slow down and move closer together.

How does pressure affect density?

As pressure increases, the density of a substance also tends to increase. This is because pressure compresses the molecules of a substance closer together, reducing the volume they occupy without changing the total mass. This results in a higher density as more mass is packed into a smaller space under higher pressure conditions.

Give an example of a substance with a high density.

Gold is an example of a substance with a high density. Gold has a density of 19.3 g/cm³, making it one of the densest elements.

Give an example of a substance with a low density.

One example of a substance with a low density is helium. Helium is a light, colorless, and odorless gas that has a density much lower than that of air, which is why helium balloons float in the air.

How does the density of a solid compare to the density of a liquid or gas?

The density of a solid is generally higher than the density of a liquid or gas. This is due to the closer arrangement of particles in a solid compared to the more spread-out arrangement in a liquid or gas. Solids have a fixed shape and volume, with particles tightly packed together, leading to a higher density. In contrast, liquids and gases have particles that are more spread out, resulting in lower densities.
