Chemistry - Ideal Gas Question with Solution | TestHub

Question Explanation: Choose correct graph.

Concept: This question is based on graph of ideal gas equation.

Solution:

From graph

P and n = constant

$$\frac{V_1}{T_1}=\frac{V_2}{T_2}$$

(1) $\frac{22.4}{273}=\frac{38.8}{373}$

.082 ≠ .104   (Incorrect)

(2) $\frac{22.4}{273}=\frac{28.6}{373}$

.082 ≠ .076  (Incorrect)

(3) $\frac{22.4}{273}=\frac{30.6}{373}$

.082 = .082  (Correct)

(4) $\frac{22.4}{273}=\frac{14.2}{373}$

.082 ≠ .038  (Incorrect)

Final Answer:

The correct option is (C)
