Which one of the following graphs is not correct for ideal gas?
d = Density, P = Pressure, T = Temperature
d = Density, P = Pressure, T = Temperature
Show Hint
- II
- III
- I
- IV
The Correct Option is A
Solution and Explanation
Graph I: d vs T at constant P is a decreasing hyperbola (\(d \propto 1/T\)), correct.
Graph II: d vs T is drawn as a straight line with positive slope, but d decreases with T, so this is not correct.
Graph III: d vs 1/T is a straight line (\(d \propto 1/T\)), correct.
Graph IV: d vs P is a straight line (\(d \propto P\) at constant T), correct.
So the incorrect graph is II.
Answer: (1) II

- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
