Resumen del Recurso
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
