What is the physical state of water at :

$(a)$ $250\,^oC $

$(b)$ $100\,^oC$ ?

Option A

Option B

Option C

Option D

Solution

As the boiling point of water is $100\,^oC$ so

$(a)$ at $250\,^oC$, the state of water will be steam or water vapour, i.e., gaseous state.

$(b)$ at $100\,^oC$, there will be a transition of liquid state into the gaseous state. So, at this temperature, the state is/may be liquid as well as gaseous.
