Unit 1 Flashcard Review

Front

What is density?

Back

Density is the mass of an object divided by its volume, typically expressed in g/cm³.

Front

How do you determine if an object will sink or float in water?

Back

An object will sink if its density is greater than that of water (1 g/mL) and float if its density is less.

Front

What is the formula to calculate density?

Back

Density = Mass / Volume.

Front

If an object has a density of 6 g/mL, will it sink or float in water?

Back

It will sink because its density is greater than that of water.

Front

What is the unit of measurement for density?

Back

The unit of measurement for density is g/cm³.

Front

What happens to the density of a substance if you change its amount?

Back

The density of a substance remains constant regardless of the amount.

Front

What is volume?

Back

Volume refers to the amount of space that matter occupies, measured in liters (L) or milliliters (mL).

Front

How do you calculate the density of an irregularly shaped object?

Back

To calculate density, measure the mass of the object and the volume of water it displaces when submerged.

Front

If a piece of gold has a mass of 27 g and displaces 3 mL of water, what is its density?

Back

Density = Mass / Volume = 27 g / 3 mL = 9 g/mL.

Front

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

Back

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