Solids, Liquids and Gases Flashcards
What are the three states of matter?
- solids
- liquids
- gases
Examples of Solids,Liquids and Gases
- solid: ice
- liquid: water
- gas: water vapour
Movement of Particles in a Solid
vibrate in fixed positions
Movement of Particles in a Liquid
move around and slide past each other
Movement of Particles in a Gas
move freely and constantly collide
Energy of States of Matter
- solid: low energy
- liquid: medium energy
- gas: high energy
What is the name of the interconversion from a solid to liquid?
melting
How does melting affect the particles?
- gain kinetic energy
- vibrate faster
- particles weaken forces of attraction
- regular arrangement is broken down
- particles slide past each other
What is the name of the interconversion from a liquid to a solid?
freezing
How does freezing affect the particles?
- lose kinetic energy
- forces of attraction stronger
- regular arrangement
- particles can no longer slide past each other
What is the name of the interconversion from a liquid to a gas?
boiling
How does boiling affect the particles?
- gain kinetic energy
- move further apart
- forces of attraction completely broken
- particles escape from liquid (evaporation)
What is the name of the interconversion from gas to a liquid?
condensing
How does condensing affect the particles?
- lose kinetic energy
- forces of attraction move particles closer together
- clump to form liquid
What is the name of the interconversion from solid to gas
subliming
