This is probably review: Matter can change from one form to another match the name to the phase change.

Draggable item		Corresponding Item
gas to liquid		boiling or evaporation
liquid to solid		melting
gas to solid		freezing
Solid to gas		condensation
liquid to gas		deposition (snowing, frost)
solid to liquid		sublimation (dry ice)

ok, if you are not 8th grade or honors, you can be done. 8th grade and honors, watch this.
Do. you have any questions?

Whether something is a gas, a solid or a liquid depends on the material, the temperature and the pressure. Each material has a different diagram like this that shows what phase something would be at a specific temperature or pressure. where do you think the triple point is on this chart? circle the triple point on the chart.

The phase diagram below represents the phase diagram for an unknown substance.

null

The name of the change of state for this substance if it was cooled from 0° to -50°, staying at the pressure1000 would be

The name for the change in state for this substance if it were heated up from -75 ℃ and 150.0 kpa to -40 ℃ and 200 kpa would be called . Make sure you match your pressures to pressure on the graph.

If you are interested, you can figure out what a supercritical fluid is on your own and come and explain it to me.

Do you think you can explain why pressure changes the state of a solid just like temperature?

yes

no

do you think you can explain how a phase diagram works to the class?

yes

no
