Slide 1 - Open vraag

RECAP 2: How are the arrangement of particles for each matter?

Slide 2 - Open vraag

Change of state
Materials changes state all the time around us
The state of substance depends on the environment that surrounds and affect it

Slide 3 - Tekstslide

how matter change it's state?

Slide 4 - Woordweb

Name a few examples where changes of state of matter occur

Slide 5 - Tekstslide

Can you name a few process that cause change of state to happen

Slide 6 - Open vraag

Melting and boiling point
Melting point is the temperature at which solid changes state to become liquid
Boiling point is temperature at which it changes state from liquid to gas

Slide 7 - Tekstslide

Melting point is the same as freezing point

Slide 8 - Poll

Can you see why?

Slide 9 - Open vraag

Liquids can change to gases below their boiling point
During evaporation, liquid absorbs energy from the surrounding which cool down
Think about the feeling of alcohol on your skin
Do you feel cooler after you sweating during exercise?

Slide 10 - Tekstslide

Water evaporate becomes liquid causing high humidity in the air
Low humidity causes dry skin and breathing problems

Slide 11 - Tekstslide

Slide 12 - Tekstslide

Water vapour condense to form liquid, usually in form of droplets
When is the last time you encounter the event of condensation?
Condensation may causes mould on clothes and rotting of wood

Slide 13 - Tekstslide

Slide 14 - Tekstslide

Substance sometimes skip a phase when change of phase happens
Example: gas to solid or solid to gas
Have you seem the process of sublimation?

Slide 15 - Tekstslide

Slide 16 - Tekstslide

Slide 17 - Tekstslide

What happen to the particles during change of state?
