PHYSICAL CHARACTERISTICS OF WATER

1. Pure water 2. Exis in three states 3. Tests for presence of water - colourless, i. solid (ice) - changes anhydrous cobalt - odourless, ii. Liquid (water) chloride paper blue to pink - tasteless iii. Gas (water vapour/steam) - changes anhydrous copper Sulphate white to blue

4. Freezing point = 0C 5. Boiling point = 100C (Temperature liquid ( temperature liquid 6. Density at 4C change to solid) change to gas) = 1 g/cm

7. weak heat conductor 8. poor electrical conductor
