|---|---|---|---|---|---|
| Phase of matter | the form in which particles are arranged and move
🗑
|
||||
| boiling point | the temperature at which a substance changes from a liquid to a gas
🗑
|
||||
| melting point | the temperature at which a substance changes from a solid to a liquid
🗑
|
||||
| A solid has ... | a definite shape and takes up a definite amount of space
🗑
|
||||
| A solid's particles are... | closely packed together and have some energy, and move back and forth but do not change places
🗑
|
||||
| A liquid... | does not have a definite shape but takes up a definite amount of space
🗑
|
||||
| A liquid's particles are... | not held in place but are able to slide past one another
🗑
|
||||
| A liquid takes the shape... | of the container
🗑
|
||||
| gases are... | invisible and do not have a definite shape
🗑
|
||||
| Gas takes the shape | of the container and expands to fill whatever space is available
🗑
|
||||
| Gas particles are... | very far apart from one another and move in all directions
🗑
|
||||
| in the gas state, water is called... | water vapor
🗑
|
||||
| gas does not take up a definite amount of... | space
🗑
|
||||
| Energy can cause the particles in a substance to move | faster and farther apart.
🗑
|
||||
| Substances change phase (state or form) when enough heat is | added or taken away.
🗑
|
||||
| Phase changes are examples of physical changes that can be reversed by | adding or removing energy.
🗑
|
||||
| Every substance changes phases at a different... | temperature
🗑
|
||||
| The melting point and boiling point of a substance are both physical properties that help | identify the substance.
🗑
|
||||
| The temperature at which a substance melts is the same temperature at which it freezes, or changes from a | solid to a liquid.
🗑
|
||||
| The temperature at which a substance changes from a liquid to a gas is also the temperature at which the substance changes from a | gas back into a liquid.
🗑
|
||||
| Substances have different melting and boiling points that are much different from | the melting and boiling points of water.
🗑
