Degree of freedom temperature pressure and concentration must be specified inorder to define the system completely water vmcan exist in three phases solid liquid and gas in this diagram the curve represents the equilibrium between vapour at different temperatures the atmospheric pressure critical pressure at triple point of  and this was the periodic table for you guys so enjoy this like comment and please don't share this it is a class of organic compound having atleast one hetero Aton that is Tom other than carbon in the cyclic ring system the most common heterogeneous compounds are classified as saturated and unsaturated the saturated.
