Year 5 Chemical Sciences

Effect of Temperature on State

Gases Have Masses

Changing States (chemical, not geopolitical)

Secretive Substances

  1. States of Matter
  1. Gases Take Up Space?
  1. Boiling/Evaporation and Condensing
  1. Glass

E4E on Plasma

  1. Temperature and States of Matter

Introduce idea of particles

Can be packed together and unmoving, like a brick wall - solid

Can be close together but able to flow, like sand - liquid

Individual particles bouncing around, like bumper cars? - gas

Describe temperature as "how much a particle can move"

Explain how the amount of movement determines which state it prefers

Explain how a gas still takes up space and has weight

Compare 1kg of cheese (Is that an aus thing?) with 1kg of air

Balloons and Bubbles

Very basic pressure description

  1. Freezing and Melting
  1. Subliming and Depositing
  1. Non-Newtonian (need new name)
  1. Supercritical Fluids (need new name)

Boiling when hot, evaporating at all times

Boiling everywhere, evaporating on surfaces

Condensing happens at the same temperature, just other direction

Both happen at the same temperature, just different directions

Much rarer

Skips the middle step

Solid, but non-traditional

NOT A SLOW MOVING LIQUID

Acts like a solid or liquid depending on how hard you push it

Acts like a liquid AND a gas because it's moving around so fast that it don't know which way what
