Properties of Water (H2O)
- Water has the highest specific heat capacity of all liquids (1 cal/g/deg
C)
- Solid water (ice) is less dense than liquid water.
- Water is one of the few inorganic substance that is a liquid at room
temperature and 1 atmosphere
- Water has the highest surface tension of all liquids except mercury.
- Water demonstrates strong capillary action.
- Water has the greatest thermal conductivity except for mercury
- Water is the most universal solvent
- Water has a high heat of vaporization and heat of fusion.
- Water is the only molecule with vibrational overtones in the visible
region (This is why large bodies of water are blue)
- Water has a pH of 7 and can act as an aci or a base.
- Water exists as a liquid over an
important range of temperature from 0 - 100° Celsius. This range
allows water to remain as a liquid in most places on the Earth.
- Water is the only substance on Earth that exists as a solid, liquid,
and a gas.
