Density

Front

What is density?

Back

Density is the mass of a substance divided by its volume, typically expressed in grams per cubic centimeter (g/cm³).

Front

How is density calculated?

Back

Density is calculated using the formula: Density = Mass / Volume.

Front

What is the significance of density in identifying substances?

Back

Density is a characteristic property that can help identify a substance, as it remains constant regardless of the sample size.

Front

What does inorganic mean?

Back

Inorganic refers to substances that were never living, typically including minerals and metals.

Front

What is the difference between matter and energy?

Back

Matter is anything that has mass and occupies space, while energy is the ability to do work and does not have mass.

Front

What is hardness in relation to minerals?

Back

Hardness is a measure of a mineral's resistance to being scratched, determined by comparing it to other minerals.

Front

What is the Mohs scale?

Back

The Mohs scale is a scale that ranks minerals based on their hardness, from 1 (talc) to 10 (diamond).

Front

What is the relationship between mass and volume in determining density?

Back

Density increases with mass if the volume remains constant, and decreases with volume if the mass remains constant.

Front

How does temperature affect the density of a substance?

Back

Generally, as temperature increases, the density of a substance decreases due to expansion, while cooling typically increases density.

Front

What is the principle of buoyancy related to density?

Back

An object will float in a fluid if its density is less than the density of the fluid, and sink if its density is greater.
