There would be no life on earth without water.
Water is a liquid at room temperature due to hydrogen bonding.
Water has a high heat of vaporization. Water has a high surface tension. The amount of energy required to overcome the attraction of molecules of a liquid for one another at the surface. Water is an excellent solvent, often referred to as the universal solvent. Vapor Pressure - the pressure in the gaseous state of those molecules that have escaped from the liquid at a given temperature.
