Solids Liquids & Gases Mrs Maggs Flashcards
In solids…
Particles vibrate in their fixed position
In liquids…
Partial can move slowly from their positions but are always in contact with other partials
In gases…
Particles move very quickly colliding with other particles
Intermolecular forces
Forces between molecules
Intermolecular forces are very strong
Solids
Intermolecular forces are still strong but not as strong as solids
Liquids
Intermolecular forces are very weak
Gases
State of matter
Solid to liquid to gas and back again
Thermal expansion when it is cold
The particles would contract to much and therefore break
Thermal expansion when it is hot
The particles will vibrate causing kinetic energy pushing the rails out overtime causing the rails to break
Viscosity
The ability of liquids and gases to flow
Volume
The measurement of a substance
Compress
Squashed with a force
Evaporation
Change from a liquid to a gas at the surface of the liquid
Boiling
When a liquid changes state to a gas at its boiling point
