Why water is called as ‘Elixir of Life’?
टीपा लिहा
उत्तर
- Water is in liquid form at room temperature and is the best solvent for most of the solutes.
- In pure form, it is the inert inorganic compound with neutral pH. Due to this, water is the best transporting medium for dissolved minerals and food molecules.
- It is the best aqueous medium for all biochemical reactions occurring in the cells.
- It is an essential raw material for photosynthesis.
- Water has high specific heat, high heat of vaporization, and high heat of fusion. Due to this, it acts as a thermal buffer.
- Water molecules have good adhesive and cohesive forces of attraction.
- Due to high surface tension and high adhesive and cohesive force, it can easily rise in the capillaries. This is why water is called as ‘Elixir of Life'.
