States of Matter - Structure and Bonding Flashcards
Freezing
Liquid to solid
Melting
Solid to liquid
Evaporating
Liquid to gas
Condensing
Gas to liquid
What happens when a material is heated?
The intermolecular forces of attraction get weaker
Boiling properties
- Bubble
- Temperature remains constant
- Faster
- All particles engaged
Evaporation properties
- Slower
- Surface is only heated
- Happens naturally
- Occurs at any temperature
- No bubbles
- Temperature can flunctuate (vary)
What is sublimation?
Solid turns straight to gas
What is deposition?
Gas straight to solid
What happens to a solid when it is melting?
It stays at the same temperature, because the energy is weakening the intermolecular forces of attraction.
What is a mixture?
two or more different substances, not chemically joined together.
What is filtration?
Used to separate a micture of insoluble solid and a liquid
Whats distillation?
Separate out the solvent from a solution
Whats crystallisation?
Separte a solute from a solution
Whats chromotography?
Separate mixtures according to solutbility
