|---|---|---|---|---|---|
| Heat | Form of energy that can be transmitted from one place to another through conduction, convection, or radiation – condition of being hot
🗑
|
||||
| Physical Change | Change that occurs in matter and can be returned to its original condition
🗑
|
||||
| Expansion | The increase in volume of matter that occurs when matter is heated
🗑
|
||||
| Contraction | The decrease in volume of matter due to the lack of heat
🗑
|
||||
| Temperature | The measurement of how hot an object or substance is
🗑
|
||||
| Conduction | Transmission of heat by transferring energy from one particle to another
🗑
|
||||
| Convection | Transfer of heat from one place to another by the circulation of currents of heated particles of a gas or liquid
🗑
|
||||
| Radiation | Energy (heat) given off by electromagnetic waves (waves we can’t see)
🗑
|
||||
| Phase Change | The changing from a solid to a liquid to a gas or a gas to liquid to solid through change in energy
🗑
|
||||
| Solid | Has definite volume and shape, and its particles are closely packed and tight with little energy
🗑
|
||||
| Liquid | Has definite volume and no definite shape, particles are not as closely packed and tight as solids – has some energy
🗑
|
||||
| Gas | No definite shape or volume, particles a loosely packed and moving with a lot of energy
🗑
|
||||
| Melting | Changing from a solid to a liquid- Energy increase
🗑
|
||||
| Freezing | Changing from a liquid to a solid – Energy decrease
🗑
|
||||
| Boiling | Changing from a liquid to a gas at the substance’s boiling point- Energy increase
🗑
|
||||
| Evaporation | Changing from a liquid to a gas from the surface of a liquid
🗑
|
||||
| Condensation | Changing from a gas to a liquid – Energy decrease
🗑
|
||||
| Sublimation | Changing from a solid to a gas skipping the liquid phase
🗑
|
||||
| Freezing/Melting Points | 0 degrees Celsius (Water)- freezing
Greater than 0 degrees - melts
Less than 0 degrees - freezes
🗑
|
||||
| Boiling Point | Water – 100 degrees Celsius
The point at which a liquid turns into a gas
🗑
|
||||
| Conservation on Mass | No matter is gained or lost when a substance undergoes a phase change
🗑

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.
