Question

Define state function with suitable examples​

Answer 1

Answer:

STATE FUNCTION

• Those properties of system which depends only initial and final state not on path of the process.
• Example - internal energy (E/U) , enthalpy (H) , entropy (S) , Gibbs free energy (G), pressure , temperature , volume , length etc.

Intrnal energy (I/E)

• The sum of all type of energy present in system is called internal energy.

Enthalpy

• The total energy related to any system is called enthalpy.

Entropy

• The randomness or disorderness related to any system is called entropy.

Gibbs free energy

• The minimum energy used in useful work is called Gibbs free energy.
