Question

Give an example of a state function and explain why it is a state function

Answer 1

• A specific state which is defined being a property without the path taken to achieve that state based on it, is understood as a state function. 
• While the functions whose value is based on the direction taken among two states are named direction or path functions, on the other hand.
• The system's thermodynamic condition relates to the current material in temperature, pressure and quantity.
• State functions rely only on certain requirements and not on how they have been achieved. State functions for an instance, involve entropy, density, enthalpy and internal energy.
• They are known as state functions as they quantitatively define a thermodynamic system's equilibrium condition, regardless of how the system landed in that condition.
