Water
- Three changes of state are Solid, Liquid and Gas
- The higher the temporature, the more energy the the thing has
- Gas spreads around and does not touch
- Lquids are looser and move around
- Solids are close together and vibrate
- A common test for finding the presence of water
- Using Cobalt Chloride, soak filter paper in it then dry out paper. Put over object being tested
- Cobalt Chloride: COBALT is blue. WATER in the sea is blue
- Observations of appearances are opaque, translucent and transparent
- Solute, solvent and solution
- A solution is typically a mixture of a liquid and a dissolved solid
- A solvent is the thing that a solute is being dissolved in
- A common solution is water and salt
- A solute is usually the solid being dissolved
- Being soluable means that the solute can dissolve
- SOLUable + SOLUte= SOLU
- Obtaing Clean water
- Layer of SEDIMENT at the bottom of the container
- DECANTING by carefulling pouring just the water into other container
- Pour dirty water through filter paper into a conicle flask
- RESIDUE is left in filter paper and FILTRATE (clean water) is now in flask
- FILTRATE because that is what has been FILTERED through
- Water Distillation
- Heat water so it evaporates and hits solid object and cools down
- Water goes from liquid to gas to liquid to leave salt residue behind
- water distillation is when you receive clean water from salty
