Question | Answer |
---|---|
A solid has __________ shape and __________ volume. | definite shape and definite volume |
A liquid has _________ shape and _________ volume. | NO definite shape and definite volume |
A gas has ___________ shape and __________ volume. | NO definite shape and NO definite volume |
Which state of matter moves the fastest? | gas |
Which state of matter moves the slowest? | solid |
To change a substance from one state to another, you must . . . | add or remove energy. |
What is the melting point? | Temperature at which a substance changes from a solid to a liquid |
What is the boiling point? | Temperature at which the liquid becomes a vapor |
What happens at the same temperature as freezing? | melting |
Which state of matter has the highest energy? | plasma |
Gas to liquid | condensation |
Liquid to gas | evaporation |
Solid to liquid | melting |
Liquid to solid | freezing |
Matter is anything that . . . | has mass and takes up space. |
Describe the arrangement and movement of particles in a liquid. | They are close together and are able to slip past one another. |
Describe the arrangement and movement of particles in a gas. | They spread and fill the volume of the container that holds them. |
Compare the temperature of plasma and gas. | Plasma is hotter than gas. |
The three phases of matter differ from each other in their . . . | speed of movement; energy |
As something gets warmer, it . . . | absorbs heat energy and moves farther apart. |
As something gets cooler, it . . . | releases heat energy and moves closer together. |
Vaporization is . . . | a phase change from a solid or liquid that happens when heat is applied; happens above the boiling point |
Evaporation is . . . | a type of vaporization that happens at the surface of a substance when the substance is changing from a liquid to a gas; happens below the boiling point |
