हिन्दीThe following graph represents the T-V curves of an ideal gas (where T is the temperature and V the volume) at three pressures \( P_1 \), \( P_2 \) and \( P_3 \) compared with those of Charles's law represented as dotted lines. Then the correct relation is:
View Answer & Solution
Correct answer · Option B
\( P_1 > P_2 > P_3 \)
Explanation
From the ideal gas equation \( PV = nRT \), we get \( \frac{T}{V} = \frac{P}{nR} \). Thus, the slope of the T-V graph is directly proportional to pressure \( P \). Since slope line 1 > slope line 2 > slope line 3, we have \( P_1 > P_2 > P_3 \).
