Density & Conservation of Matter- Burchac

Front

What is density?

Back

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

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What is the density of water?

Back

The density of water is 1 g/cm³.

Front

What happens to objects with a density less than water?

Back

Objects with a density less than water will float.

Front

What happens to objects with a density greater than water?

Back

Objects with a density greater than water will sink.

Front

What is the principle of conservation of matter?

Back

The principle of conservation of matter states that matter cannot be created or destroyed in a closed system.

Front

If 50g of salt is added to 200g of water, what is the total mass of the solution?

Back

Total mass = 50g + 200g = 250g.

Front

What is a common unit for measuring volume in chemistry?

Back

Common units for measuring volume include liters (L) and cubic centimeters (cm³).

Front

What is the relationship between mass, volume, and density?

Back

Density is a ratio of mass to volume; as mass increases with constant volume, density increases.

Back

Cork is an example of a substance that is less dense than water.
