Solution

The correct option is A $P$
$Solution :$
the triple point is the point where the temperature and pressure of the "three states of matter " co-exist in equilibrium
here in the given figure P is the point where temperature and pressure coincide of all the three states

Hence THE CORRECT OPT: C

The triple point is when ice, liquid water, and water vapour coexist in a dynamic equilibrium.

The triple point requires low temperatures and high pressures.

Q. For many substances, there exists a temperature

T_{t r}

. and a pressure ptr at which all the three phases of a substance (gaseous, liquid, and solid) are in equilibrium. These temperature and pressure are known as the triple point. For example,

T_{t r} = {0.0075}^{\circ} C

p_{t r} = 4.58 m m

Hg for water. The latent heat of vaporization of water at the triple point is

q = 2.48 \times 10^{3} k J / k g

, and the latent heat of fusion of ice is

λ = 0.34 \times 10^{3} k J / k g
