States Of Matter IGCSE CHEMISTRY
- there are 3 states of matter
- SOLIDS: particles are arrenged in neat rows, they are all touching, they cant move they vibrate
- LIQUIDS: the particles are all touching,free to move
- GASES: particles are very far apart but are free to move
- experiment:
- water evaporated
- gas condensed
- ice melted
- water evaporated
- SOLIDS: particles are arrenged in neat rows, they are all touching, they cant move they vibrate
- diffusion
- diffusion is the random movement of particles from a higher concentration to a lower concentratuon
- diffusion is much faster in gases than liquids because there is more space between particles
- in hot water the particles are vibrating more and bump more between each other
- diffusion is the random movement of particles from a higher concentration to a lower concentratuon
- elements, compounds, mixtures and molecules
- ATOMS: it is the smallest thing that an object can be broken down into
- ELEMENTS: a substance made up of only one type of atom
- COMPOUNDS: two or more different atoms chemically bonded together
- MIXTURE: two or more atoms mixed together but not chemically bounded
- MOLECULE: when two or more atoms are chemically bonded a molecule can be a compound or an element
- ATOMS: it is the smallest thing that an object can be broken down into
- solubility
- SOLUBLE: something that can be disolved
- INSOLUBLE: something that cannot be disolved
- SOLUTE: solid that disolves
- SOLUTION: mixture of the solute and solvent
- SATURATION: nothing more can be dissolved if the solution is saturated
- experiment: add spatulas of salt to water until it reaches the saturation point
- experiment: add spatulas of salt to water until it reaches the saturation point
- EXPERIMENT: add salt/ potassium n to ethanol/ water
- to calculate the solubility: mass of solute/ volume of solvent
- SOLUBLE: something that can be disolved
- Separating mixtures
- filtering: an insoluble solid from a liquid (eg. sand and water)
- evaporation: a soluble solid from a liquid
- sieving: solids of different sizes( e.g sand and pebbles)
- distillation: a somvent from its solution(e.g ethanol from wine)
- chromotography: a mixture of dyes (e.g yellow and red from orange)
- filtering: an insoluble solid from a liquid (eg. sand and water)
