Triple Fun with Triple point!
How many of the following statements are correct ?
-
At Triple point all three phases of substance (i.e. solid , liquid and gas ) exist together.
-
Triple point of water is exact.
-
At Triple point of water, The total pressure of the container should be 611.657 Pa (approx).
-
Triple point corresponds to the minimum temperature at which the liquid water can exist.
-
Triple point corresponds to the maximum pressure at which liquid water can exist.
-
Below Triple point pressure if solid is heated at constant pressure then solid ice first transforms to vapour then to liquid water.
-
It is possible to have phase transition like Solid ice to water vapour to liquid water at required conditions.
-
Triple point is same as Critical point.

Official Defination .
By this only , Fundamental Quantity Kelvin is defined .
Partial pressure of water vapour should be that , not total pressure .
Water Shows anomalous property in this case , at temperature less than triple point temperature when pressure is applied then water vapour first changes to solid ice and then to liquid water .
Its the minimum pressure at which liquid water can exist.
Below Triple point pressure , when solid ice is heated then it sublimes.
See point 4.'s explanation .
Not the same !
