Question

What is path and state function of chemical thermodynamics

Answer 1

Any property which depend only on initial and final state of a system but independent of path followed is called state function.

any property who is depends on Path is called path function.

Answer 2

Hey!

Path function :
The thermodynamic quantity whose value depends on the path of transition is called Path function.

Example : Heat and work.

State function :
The thermodynamic property whose value depends only on the state variables of the system is called state function.

Example : Internal energy, enthalpy, entropy and free energy.

=> • The macroscopic properties whose values decide the state of the system are called state variables.
Example : Pressure, volume, temperature, number of moles.

=>• The properties of the system that are due to collective behaviour of the individuals are called Macroscopic properties.
Example : Pressure, volume, temperature, density, viscosity, surface tension.

hope it helps..!
