States of matter (chem)

• Solids have strong forces between particles, so they have a fixed shape and volume. They vibrate on the spot and the hotter the solid the more it vibrates.
• Liquids have weak forces between particles and can flow easily. They have a definite volume but don't have a definite shape. They are constantly moving and the hotter the liquid, the faster it moves.
• Gases have a very weak force between particles and therefore they can move freely through the space. They don't keep their shape or volume. They are constantly moving and the hotter the gas gets, the faster it moves
• solid to liquid = melting
• liquid to gas = evaporation/boiling
• gas to liquid = condensation
• liquid to solid = freezing
• solid to gas = sublimation
• gas to solid = decomposition
• solution = a mixture of a solute and a solvent that doesn't separate
• solute = substance being dissolved
• solvent = the liquid a solute dissolves into
• saturated solution = a solution where no more solute can be dissolved
