Hydrogen
(i) The high heat of vaporisation and heat capacity of water are responsible for moderation of the climate and body temperature of living beings.
(ii) High specific heat capacity of water enables it to absorb heat of various biochemical and physiological reactions, going on inside the body, with the minimum rise of temperature.
(iii) Water has a high dipole moment (μ = 1.84D). So, water is an ideal medium for the dissolution of a wide variety of compounds.
(iv) Water is an ideal solvent for transportation of minerals and other nutrients for plant and animal metabolism.
(v) Water is an essential component for the photosynthesis in plants which releases O2 in the atmosphere.
