|---|---|---|---|---|---|
| melting | a change in state from a solid to a liquid; the opposite of freezing
🗑
|
||||
| melting point | temperature at which a solid becomes a liquid
🗑
|
||||
| freezing | a change in state from a liquid to a solid; the opposite of melting
🗑
|
||||
| vaporization | change in state from a liquid to a gas; the opposite of condensing
🗑
|
||||
| evaporation | vaporization that takes place at the surface of a liquid
🗑
|
||||
| boiling | vaporization that occurs both at the surface and below the surface
🗑
|
||||
| boiling point | the temperature at which a liquid boils
🗑
|
||||
| condensation | a change in state from gas to a liquid; the opposite of vaporization
🗑
|
||||
| sublimation | change that occurs when the particles on the surface of a solid gain enough energy that they form a gas
🗑
|
||||
| What happens to the particles of a solid as it melts? | At a solid’s melting point, its particles vibrate so fast that they break free from their fixed positions.
🗑
|
||||
| What happens to the particles of a solid as it sublimes? | During sublimation, particles of a solid do not pass through the liquid state as they form a gas.
🗑
|
||||
| What happens to the particles of a liquid as it freezes? | At a liquid’s freezing point, its particles are moving so slowly that they begin to take on fixed positions.
🗑
|
||||
| What happens to the particles of a liquid as it vaporizes? | Vaporization occurs when the particles in a liquid gain enough energy to move independently.
🗑
|
||||
| What happens to the particles in a gas when it condenses? | Condensation occurs when particles in a gas lose enough thermal energy to form a liquid.
🗑
|
||||
| Particles in which state of matter have the greatest amount of thermal energy? | gas
🗑
|
||||
| Which two changes in state happen at the surface of a substance? | sublimation and evaporation
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
