Unit 1 Matter Volume Density Holden Intro TEST

Front

What is density?

Back

Density is a measure of the amount of matter in a given volume of a substance, typically expressed in grams per cubic centimeter (g/cm³).

Front

How do you calculate density?

Back

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

Front

What is the density of a substance if its mass is 14g and its volume is 2cm³?

Back

7 g/cm³.

Front

Why do some substances float on water?

Back

Substances float on water if they are less dense than water.

Front

What happens to the density of an object if its mass increases while its volume remains the same?

Back

The density of the object increases.

Front

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

Back

Mass is the amount of matter in an object, volume is the space it occupies, and density is the mass per unit volume.

Front

If a metal ring has a mass of 26.7 grams and a volume of 3 cm³, what is its density?

Back

8.9 g/cm³.

Front

What is the definition of volume?

Back

Volume is the amount of space that a substance or object occupies, typically measured in cubic centimeters (cm³) or liters (L).

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is an example of a substance that is less dense than water?

Back

Oil is an example of a substance that is less dense than water and will float on its surface.
