Question

The limitation of the first law of Thermodynamics is that it cannot tell us the direction of the process.
If true enter 1, else enter 0.

• A. 1

Answer 1

The correct option is A 1
First law of thermodynamics states that energy is conserved. Direct consequence of this statement is U is state function. This implies between any two fixed state, there can be infinite process or path, but $\Delta U$ in all process will remain the same.(Property of a function of state).
The major limitation of the first law of thermodynamics is, its inability to deal with the direction of the process and the extent of change.
