Question

Assertion (A): At constant pressure when a gas is heated from 40 to 41°C, the increase in volumes is 1/273 of its initial volume at 273 K
Reason (R):Volume coefficient of gas is 1/273 /°C

Moderate

A

Both assertion (A) and reason (R) are correct and R gives the correct explanation
B

Both assertion (A) and reason (R) are correct but R does not give the correct explanation
C

A is true but R is false
D

Both A and R are false

Solution

$\begin{array}{l} α = \frac{ΔV}{VΔt}, Δt = 1^{\circ} C \\ α = \frac{1}{273 {.15}^{0} C} \end{array}$
