Sublimation...?

Let's take a look at this

Check Question 1-2-3

The change from gas to liquid we call...

1. evaporation
2. condensation
3. melting
4. sublimation

The change from solid to gas we call

1. sublimation
2. evaporation
3. freezing
4. condensation

The change from liquid to gas we call

1. condensation
2. freezing
3. evaporation
4. deposition

The change from liquid to solid we call

1. melting
2. freezing
3. sublimation
4. deposition

Changes of states

-Melting - changing from solid to liquid

-Freezing - changing from a liquid to a solid

-Evaporation - changing from liquid to gas

-Condensation - changing from gas to a liquid

-Deposition - changing from gas to a solid

-Sublimation - changing from a solid to gas

Check Q 3

melting

deposition

condensation

freezing

evaporation

sublimation

You only have to use two out of three

Evaporation

Condensation

Sublimation

Question 4

Explain why the melting point and freezing points of a substance are at exactly the same temperature

That is the tipping point where a little above it is a liquid and a little below the substance will be frozen, it is where one phase goes over in the other

Question 5

5. Evaporation always occurs at all temperatures because there will always be some particles moving fast enough to break free from the liquid. This explains why clothes on the line will eventually dry, even on cold days.

Task: Finish page 6 (and 7)

Question 6

Explain how:

a) Snow is formed when it is really cold and the rain droplets have turned solid

b) Dew: water vapour in the air will condense on a cold night to form droplets of liquid

c) Frost: Liquid water freezes to form frost on cold mornings

Question 7 page 6: state changes

a) Ice cream starts to drip

Solid to liquid → Melting

b) The bathroom mirror gets foggy

(Water vapour) gas turns liquid → condensation

c) Steam coming from a kettle

Liquid to gas → evaporation

Page 6 - Question 8

So far... Is this a difficult topic for you?
:( = yes :) = no

😒🙁😐🙂😃

Classwork

Finish the questions on page 7. If you already did, take a careful look at them again and discuss them with your classmates.
