Is work a state or path function?
Heat and work are path functions Heat (q) and work (w) are path functions, not state functions: They are path dependent. They are energy transfer → they are not intrinsic to the system.
Is work an example of a state function?
Work and heat are major examples that are not state functions. Major examples of state functions are internal energy, entropy, enthalpy, free energy, and Heimholtz energy.
What are the 4 state functions?
Examples of state functions include density, internal energy, enthalpy, entropy. Such a relation cannot be written for path functions, especially since these cannot be defined for the limiting states. Path functions depend on the route taken between two states.
Why work done is a state function?
As, we know the property or a function which does not depend on the path is called a state function. Work-done in adiabatic processes is equal to the negative of change in internal energy from the first law of thermodynamics. So, it is a state function.
Is work a state property?
Therefore, if an object is dependent on its history or on the path it takes, the resulting value or property is not a state function. Even though pressure and volume are state functions, the definition of work illustrates why work is not a state function.
Is work a state variable?
In thermodynamics, a state variable is an independent variable of a state function. Examples include internal energy, enthalpy, temperature, pressure, volume and entropy. Heat and work are not state functions, but process functions.
Is work a path function?
Complete answer: So, work is a path function as different routes give different quantities. The specific volume of a substance can be defined as the ratio of the substance's volume to its mass. It does not depend on that path taken as it is measured for a state and not a route. So, it is a state function.
What type of function is work?
Work is a path function and not a state function.
