Answer 1

Answer:

Given:

Water <=> Water vapour .

This equilibrium has been provided.

Pressure has been applied on the system.

To find:

Whether Boiling Point of water increases ?

Concept:

We will focus on the formula :

PV = nRT

If we keep V and n constant , then

P ∝ T

So as we increase the pressure, the temperature also increases. Considering this, we can also say that the boiling point of water is increasing.

This theory is practically used in pressure cookers in the mountains.

Usually the air pressure is low, but when we cook in the cooker, the pressure is increased .

Hence the boiling point of water is increased . This helps in boiling of vegetables very well and helps in cooking.

Answer 2

$<font color ="green">$ANSWER:-

On the other hand, in a closed vessel or system, water and water vapour are in equilibrium at atmospheric pressure (1.013 bar) and 100°C. For any pure liquid at one atmospheric pressure, the temperature at which the liquid and vapour are at equilibrium is called the normal boiling point of the liquid.

OPTION 3 IS THE RIGHT ANSWER.
