Introduction to Matter

Click on the flashcard to see the answer



What is matter?

Matter is anything that has mass and takes up space.

What are the three common states of matter?

The three common states of matter are solid, liquid, and gas.

How is the state of a solid characterized?

A solid has a definite shape and a definite volume.

How is the state of a liquid characterized?

A liquid has a definite volume but takes the shape of its container.

How is the state of a gas characterized?

A gas has no definite shape or volume and expands to fill its container.

What is mass?

Mass is the amount of matter in an object.

What is volume?

Volume is the amount of space that matter occupies.

What instruments can be used to measure mass?

A balance or scale can be used to measure mass.

What units are commonly used to measure mass?

Mass is commonly measured in grams or kilograms.

What is density?

Density is the mass of a substance per unit volume.

Why does ice float in water?

Ice floats in water because its density is less than that of liquid water.

What is the formula to calculate density?

The formula to calculate density is mass divided by volume (Density = Mass/Volume).

What is an example of a physical change in matter?

An example of a physical change is melting ice into water.

What is an example of a chemical change?

An example of a chemical change is the rusting of iron.

Why is matter important in science?

Matter is important because it is the substance that makes up all physical objects in the universe.

1. What instruments can be used to measure mass?

A thermometer or barometer

A balance or scale

A ruler or measuring tape

A compass or protractor

2. How is the state of a gas characterized?

A gas has a definite shape and definite volume.

A gas has a definite shape but no definite volume.

A gas has no definite shape or volume and expands to fill its container.

A gas has a definite volume but takes the shape of its container.

3. What is the formula to calculate density?

Density = Volume/Mass

Density = Mass/Volume

Density = Mass x Volume

Density = Volume - Mass

The three common states of matter are solid, liquid, and gas.

The three common states of matter are plasma, liquid, and gas.

The three common states of matter are solid, liquid, and plasma.

The three common states of matter are gas, plasma, and liquid.

5. How is the state of a liquid characterized?

A liquid has a definite volume but takes the shape of its container.

A liquid has no definite shape or volume.

A liquid has a definite shape and volume.

A liquid has a definite shape but no definite volume.

6. What is an example of a chemical change?

Melting ice into water

Boiling water into steam

Shredding paper

The rusting of iron

7. What is matter?

Matter is a form of energy.

Matter is anything that is a liquid.

Matter is anything that has mass and takes up space.

Matter is a type of chemical reaction.

8. What is mass?

Mass is the volume of a substance.

Mass is the density of a substance.

Mass is the temperature of a substance.

Mass is the amount of matter in an object.

9. Why does ice float in water?

Because it is colder than water.

Because it has more mass than water.

Because its density is less than that of liquid water.

Because it takes the shape of its container.
