Explain the various properties of water
Answers
Answer:
Water is a colourless, tasteless, and transparent liquid. It also has no smell.
⋅ Boiling point of pure water is 100
∘
C at 760 mm of Hg pressure. However, boiling point of water increases due to increase in pressure and presence of dissolved impurities.
⋅ Pure water freezes at 0
∘
C at 760 mm of Hg pressure. However, freezing point of water decreases due to increase in pressure and presence of dissolved impurities.
⋅ The state of water changes on heating or cooling. On heating, the state of water changes from liquid state to gaseous state (vapour). Similarly, on cooling, the state of water changes from liquid state to solid state (ice).
⋅ Water is neither acidic nor basic. It is neutral.
⋅ Water is a bad conductor of heat and electricity.
⋅ Water is an universal solvent as it can dissolve many substances in it.
