Thermodynamical Functions

Thermodynamical functions are state variables that depend only on the current state of the system and not on how the system arrived at that state. In other words, they are properties of the system that are independent of the path taken to reach a particular state.

Examples of thermodynamical functions are enthalpy, internal energy, entropy, and Gibbs energy. These functions are used to describe the behavior of a system under different conditions and are important in understanding the thermodynamics of chemical reactions and other processes.

Work Done

Work done is not a thermodynamical function. Work is a process variable that depends on the path taken to reach a particular state and is therefore not independent of the system's history. Work done is the energy transferred to or from a system as a result of a mechanical process, such as the expansion or compression of a gas.

While work done is not a thermodynamical function, it is related to other thermodynamic variables, such as pressure, volume, and temperature. For example, the work done during an isobaric process (where pressure is constant) can be calculated as the product of the pressure and the change in volume.

Conclusion

In summary, thermodynamical functions are state variables that are independent of the path taken to reach a particular state, while work done is a process variable that depends on the path taken. Enthalpy, internal energy, entropy, and Gibbs energy are examples of thermodynamical functions commonly used in thermodynamics.

Work done is a process not a function
