Question

State True or False.

Saturated vapours do not obey gas laws except Dalton's law and their pressure is independent of volume.

• A. True
• B. False

Answer 1

The correct option is A True

The given statement is True.
Saturated vapours do not obey gas laws except Dalton's law and their pressure is independent of volume. Aqueous tension depends only on temperature. When a gas is collected over water, it mixes with water vapours so the correct pressure of moist gas is given as $P_{\text{moist gas}}=P_{\text{dry gas}}+P_{\text{V.P of water}}$
