Matter Review

Front

What is density?

Back

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

Front

What does the Law of Conservation of Mass state?

Back

The Law of Conservation of Mass states that in a closed system, mass is neither created nor destroyed during a chemical reaction.

Front

If a reaction occurs in an open system, what might happen to the mass?

Back

In an open system, mass can change due to the escape of gases or the addition of substances.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

What is mass?

Back

Mass is the amount of matter in an object, typically measured in grams (g) or kilograms (kg).

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 happens to an object with a density less than that of water when placed in water?

Back

It will float.

Front

What happens to an object with a density greater than that of water when placed in water?

Back

It will sink.

Front

What is the volume of an object?

Back

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

Front

How do you measure the mass of a substance?

Back

Mass can be measured using a balance scale.
