Question

11. Assertion (A): According to gas equation,

$$\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}$$

Reason (R): On combining Boyle’s law and Charle’s law, ‘volume of a given mass of a dry gas varies inversely as the pressure and directly as the absolute temperature.’

पर्याय

• Both A and R are true and R is the correct explanation of A.

• Both A and R are true but R is not the correct explanation of A.

• A is true but R is false.

• A is false but R is true.

Answer 1

Both A and R are true and R is the correct explanation of A.

Explanation:

The gas equation follows directly from combining Boyle’s law and Charles’s law for a fixed mass of gas. Thus, both statements are true, and R explains A.
