Question

What is the physical state of water at:
a. ${250}^{o}C$
b. ${100}^{o}C$

Answer 1

a. ${250}^{\circ }C$ - The boiling point of water is ${100}^{\circ }C$. Above this temperature, water is converted into steam. Therefore, water will be in its gaseous state.

b. ${100}^{\circ }C$ - Water boils at ${100}^{\circ }C$. Water can exist in both liquids as well as gaseous states. Only after giving a sufficient amount of heat (Latent heat of vaporization), the water will convert into its vapour form.
