Question

Match the following :

List -I	List-II
A. Boyle’s law	1. $P_{wet}=P_{dry}+P_{watervapour}$
B. Avogadro law	2. $V_1=n_1\left(\frac{V_2}{n_2}\right)$
C. Charles law	3. $V_1=V_0(1+\frac{t}{273})$
D. Dalton’s law	4. $V_1=P_2\left(\frac{V_2}{P_1}\right)$

The correct match is:

• A. A-1, B-2, C-3, D-4
• B. A-2, B-3, C-4, D-1
• C. A-4, B-3, C-2, D-1
• D. A-4, B-2, C-3, D-1

Answer 1

The correct option is D A-4, B-2, C-3, D-1

Boyle's law: At constant temperature, $PV=$ constant

$\therefore P_1{V}_1=P_2{V}_2$

Avogadro's law states that "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules".

$\therefore \frac{V_1}{n_1}=\frac{V_2}{n_2}$

Charles law states that the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature if the pressure remains constant.

$=V_1=V_0(1+\frac{t}{273})$

Dalton's law: Net vapour pressure is the addition of vapour pressure of individual components.

$\therefore P_{wet}=P_{dry}+P_{watervapour}$

Hence, the correct answer is option $\text{D}$.
