Definition of state function in English:

state function


  • A quantity in thermodynamics, such as entropy or enthalpy, that has a unique value for each given state of a system.

    • ‘Consequently entropy is a state function.’
    • ‘However, heat and work are not state functions and their values are affects by the pathway taken.’
    • ‘A state function is a property of a system that does not depend on pathways, only on the initial and final states.’
    • ‘The second law defines a new state function known as the entropy.’
