Question

What is the two characteristic properties of pure water

Answer 1

Answer:

1. Nature:

Pure water is a colorless, tasteless and odorless liquid. Distilled water is pure. Drinking water has a pleasant taste because dissolved minerals and air in water make its taste better.

2. States:

Pure water exists in all the three states as solid (ice), liquid (water) and gaseous (steam or water vapor).

3. Freezing point of water:

Pure water freezes to solid ice at 00C (at 760 mm of mercury pressure)

If water contains impurities, it freezes at a temperature less than 00C. Presence of impurities lowers the freezing point. Also, at a higher pressure, water freezes at a temperature slightly less than 00C. That is why, on mountains (at a lower atmospheric pressure), water freezes at a temperature slightly higher than 00C.
