Water and solution by ZL - Coggle Diagram
Water and solution by ZL
physical characteristics of water
boiling point=100 degrees celsius
freezing point=0 degrees celsius
colourless
1g cm cubed
combination of water
mad of 2 hydrogen atoms and 1 oxygen atom
can determine through electrolysis
During electrolysis, oxygen produce at anode, hydrogen at cathode
Evaporation
process where water turns into water vapour
factors affecting rate of evaporation
humidity
surrounding temperature
movement of air
exposed area to water
Applications to daily life
clothes hung on clothes lines with large surface area and exposure to water
We get sea salt from evaporated seawater
Since microorganism cannot survive without water, seafood are to be dried to be kept longer.
types of solutions
diluted
concentrated
saturated
Solution- when solute dissolve with solvent
Solubility- how much can a solute dissolve in a solvent
solute
a solid which dissolves in a liquid
solvent
a liquid which dissolves a solid
