Solvents are extremely important for the formation maintaining life.

Their main properties are:
dissolution of chemical compounds
transport of nutrients in a cell
transport of waste,
mixing of different chemical compounds
regulation of temperature: a constant temperature is required for complex organisms

To be useful, any solvent must remain liquid within a large range of temperatures. otherwise variations in conditions on a planet or satellite of a planet will freeze or boil the solvent and living organisms will be destroyed.

Under conditions like on the Earth's surface, the temperature range for water liquid is 100°C. As the external pressure decreases(e.g. on a high mountain), the boiling point of water decreases.

S4 In order to form aggregates of organic compounds. the surface tension of a solvent relevant and water has a high surface tension. Thus water is much more appropriate for life regarding its heat capacity. heat of vaporization. surface tension and dissolving capability than other substances. Another important property of water is that it extends as it freezes. The cells of organisms that freeze w ll rupture. Putting the crew of an spaceship on ice would not help since humans consist mainly of water and the cells are destroyed by freezing. Ammonia does not expand upon freezing.
