Similarly, you may ask, what is QP in thermodynamics?

Re: Qv and Qp in delta U equations [ENDORSED] q(v) is heat at constant volume and q(p) is heat at constant pressure. Think about the formula ΔU = q+w. ΔU is the change in internal energy of system.

Beside above, which are state functions? The thermodynamic state of a system refers to the temperature, pressure and quantity of substance present. State functions only depend on these parameters and not on how they were reached. Examples of state functions include density, internal energy, enthalpy, entropy. Two examples of path functions are heat and work.

Similarly, you may ask, is QA a state function?

Heat and work are not state functions. Work can't be a state function because it is proportional to the distance an object is moved, which depends on the path used to go from the initial to the final state. Thermodynamic properties that are not state functions are often described by lowercase letters (q and w).

What is the difference between state function and path function?

State functions are defined by comparing them to path functions. As stated before, a state function is a property whose value does not depend on the path taken to reach that specific function or value. Path functions are functions that depend on the path taken to reach that specific value.
