Which of the following is NOT a path function?a)Internal energyb)Heat ...
In thermodynamics, energy can be in two forms, energy in transit and energy in storage. Energy in transit is a path function as the transfer of this energy through the boundaries of the system depends on the path which is followed by the system in the process. But energy in storage does not cross the boundaries of the system; hence it is a point function. Heat transfer as well as work transfer between the system and surrounding depends upon the path by which the process is occurred. Therefore heat energy and work energy are the path functions. Energy in storage is the internal energy. The change in internal energy (ΔE) remains constant, no matter which path is followed by a system to undergo a change of a certain state. Thus internal energy is a point function or state function.

Internal energy
Internal energy is not a path function. Path functions are those that depend on the path taken to reach a specific state, while internal energy is a state function. This means that the internal energy of a system is determined only by its current state, independent of how it arrived at that state.
Path Functions
- Path functions are quantities that depend on the path taken during a process
- Examples of path functions include heat energy and work energy
State Functions
- State functions are quantities that depend only on the current state of a system
- Internal energy is an example of a state function, as it is determined solely by the current state of the system
In conclusion, internal energy is not a path function because it is a state function that depends only on the current state of the system, not the path taken to reach that state.
