Question | Answer |
---|---|
Water freezes | 0 degrees Celsius |
Water boils | 100 degrees Celsius |
This is needed to change matter to another state. | energy |
How many states of matter? | three states of mater |
Adding heat (energy to a solid, liquid or gas causes | particles to speed up |
Removing heat energy from a solid, liquid of gas causes | particles to slow down |
The slow changing of liquid into a gas below the boiling point | evaporation |
The changing of a gas into a liquid as heat is removed | condensation |
a change in matter in size, shape or state that does not change the type of matter | physical change |
the temperature at which a substance changes state from a solid into a liquid | melting point |
what happens to the particles as water reaches its boiling point? | the particles in the water are moving faster and faster. The movement of the particles continues to increase as it changes from liquid water to a gas as water vapor. |
example of evaporation | puddle on sidewalk |
example of condensation | frost in freezer |
least dense state of matter | gas |
most dense state of matter | solid |
