Question 2

What is the physical state of water at?

(a) 250°C

(b) 100°C

Answer

(a) At 250°C water is in gaseous state since it is beyond its boiling point.

(b) At 100°C water is in the transition state as the water is at its boiling point. Hence it would be present in both liquid and gaseous states.
