Unit 4 - Properties of Matter and Bonds

Front

What is the formula for calculating density?

Back

Density = Mass / Volume

Front

What is the density of an object with a mass of 64 g and a volume of 8 cm³?

Back

8 g/cm³

Front

Define a chemical property of matter.

Back

A characteristic of a substance that can only be observed during a chemical reaction, such as flammability.

Front

What is a solid?

Back

Matter that has a definite shape and volume.

Front

What instrument is used to measure the volume of a liquid?

Back

A graduated cylinder.

Front

What is the equation for calculating the volume of a rectangular block?

Back

Volume = Length × Width × Height

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 the unit of measurement for density in the metric system?

Back

g/cm³ (grams per cubic centimeter) or kg/m³ (kilograms per cubic meter).

Front

What is a physical property of matter?

Back

A characteristic that can be observed or measured without changing the substance's chemical identity, such as color, density, or melting point.

Front

How does temperature affect the density of a substance?

Back

Generally, as temperature increases, density decreases because substances expand.
