| Question or Definition |
Answer |
| phase of matter that takes the shape of their container |
liquids and gasses |
| phase of matter that does not takes the shape of their container |
solid |
| definite shape and volume |
solid |
| definite volume, but no definite shape |
liquid |
| no definite volume and no definite shape |
gas |
| What are the states of matter? |
solid liquid gas |
| Which phases of matter cause the atoms to vibrate? |
all of them |
| What makes atoms vibrate faster |
heat |
| Do all substances have the same melting point? |
No |
| Do all substances have the same boiling point? |
No |
| changing from a solid to a liquid |
melting |
| changing from a liquid to a gas with no heat added |
evaporation |
| changing from a gas to a liquid |
condensing |
| changing from a liquid to a solid |
freezing |
| changing from a solid directly into a gas (only 6th grade needs to know this) |
sublimation |
| phrase of matter where the atoms are the closest together |
solid |
| phase of matter where the atoms move very fast and spread far apart |
gas |
| phase of matter where the atoms slide past each other and move at medium speed |
liquid |
| changing from a liquid to a gas by adding heat |
boiling |
| temperature at which a ubstance changes from a solid to a liquid (only 6th grade needs to know this) |
melting point |
| temperature at which a substance changes from a liquid to a solid (only 6th grade needs to know this) |
freezing point |
| temperature at which a substance changes from a liquid to a gas (only 6th grade needs to know this) |
boiling point |
