In thermodynamics, heat and work are :
In thermodynamics, heat and work are :
Show Hint
Heat and work depend on the process followed between two states, not just on the end states.
Updated On: Nov 4, 2026
- Path functions
- Point functions
- Extensive thermodynamics state variables
- Intensive thermodynamic state variables
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
A state (point) function depends only on the initial and final states of the system, for example \(U\), \(P\), \(V\), \(T\).
Heat \(Q\) and work \(W\) depend on the path taken between the two states, for example \(W = \int P\,dV\) differs for isothermal and adiabatic paths between the same end points.
Hence heat and work are path functions, and they are not state variables (neither extensive nor intensive).

- 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:
