Triple Fun with Triple point!

Chemistry Level 3

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 $$0.01^\circ C$$ 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.
