A balloon filled with helium (\(32^\circ\)C and 1.7 atm.) bursts. Immediately afterwards the expansion of helium can be considered as
Show Hint
A sudden burst is too fast for heat exchange (adiabatic) and happens against an unbalanced pressure difference (irreversible).

- Irreversible adiabatic
- Reversible adiabatic
- Irreversible isothermal
- Reversible isothermal
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The bursting is very rapid, so there is no time for heat to flow between the gas and the surroundings: the process is adiabatic.
The gas expands suddenly against a finite pressure difference (not quasi-statically), so it passes through non-equilibrium states and cannot be retraced: it is irreversible.
The process cannot be isothermal because the gas cools on rapid expansion.

- 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:

- Given below are two statements. One is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): With the increase in the pressure of an ideal gas, the volume falls off more rapidly in an isothermal process in comparison to the adiabatic process.
Reason (R): In an isothermal process, \( PV = \text{constant} \), while in an adiabatic process \( PV^\gamma = \text{constant} \). Here, \( \gamma \) is the ratio of specific heats, \( P \) is the pressure and \( V \) is the volume of the ideal gas.
In the light of the above statements, choose the correct answer from the options given below: - A poly-atomic molecule (C\(_3\)R, \(C_v = 4R\), where \(R\) is gas constant) goes from phase space point A (\(P_A = 10^4 \, \text{Pa}, V_A = 4 \times 10^{-3} \, \text{m}^3\)) to point B (\(P_B = 5 \times 10^4 \, \text{Pa}, V_B = 6 \times 10^{-7} \, \text{m}^3\)) to point C (\(P_C = 10^4 \, \text{Pa}, V_C = 8 \times 10^{-3} \, \text{m}^3\)).
