What are particles in solids like?
Strong forces hold water particles together so they stay in fixed positions
What are particles in liquids like?
There are attractive forces between the particles bu they can easily break and reform so particles can slide past each other
What are particles in gases like?
There are barely any attractive forces between the water particles which are free to move in any direction
Draw diagrams of solids, liquids and gases?
Do it in ur book andy
How does a solid turn into a liquid?
Melting, addition of heat
How does a liquid turn into a gas?
Evaporation, Addition of heat
How does a gas turn into a liquid?
Condensation, Removal of heat
How does a liquid turn into a solid?
Freezing, Removal of Heat
How does a solid turn into a gas?
Sublimation, Addition of heat
Why are solids more dense?
Because the atoms are in a fixed position and don’t move around, like in liquids and gases
