What are the other state functions and how do we determine them?

AI Thread Summary
State functions are properties that depend only on the current state of a system, such as temperature, pressure, and volume. Other state functions include internal energy and potential energy, which can be identified using the principle that differentials of properties are exact. To determine additional state functions, one must understand the conditions and relationships governing these properties. The discussion emphasizes the importance of recognizing the fundamental nature of state functions in thermodynamics. Understanding these concepts is crucial for analyzing thermodynamic systems effectively.

actually i know some fundamental state function such that temperature, pressure, and volume. But it's because these are the most used. Now my problem is how to know the other state function i.e what are the conditions?

Shouldn't there be a verb in that sentence?

What, exactly do you mean by "state function"?
 
Simple,
Just use the fact that differentials of properties is exact.
Now some more are internal energy potential energy etc etc.
But follow the basic rule to find it out.

Thread 'Gauss' law seems to imply instantaneous electric field propagation'

Imagine a charged sphere at the origin connected through an open switch to a vertical grounded wire. We wish to find an expression for the horizontal component of the electric field at a distance ##\mathbf{r}## from the sphere as it discharges. By using the Lorenz gauge condition: $$\nabla \cdot \mathbf{A} + \frac{1}{c^2}\frac{\partial \phi}{\partial t}=0\tag{1}$$ we find the following retarded solutions to the Maxwell equations If we assume that...

Thread 'A scenario of non-uniform circular motion'

(All the needed diagrams are posted below) My friend came up with the following scenario. Imagine a fixed point and a perfectly rigid rod of a certain length extending radially outwards from this fixed point(it is attached to the fixed point). To the free end of the fixed rod, an object is present and it is capable of changing it's speed(by thruster say or any convenient method. And ignore any resistance). It starts with a certain speed but say it's speed continuously increases as it goes...

Thread 'Do electron density waves accompany EM waves in coaxial cables?'

Maxwell’s equations imply the following wave equation for the electric field $$\nabla^2\mathbf{E}-\frac{1}{c^2}\frac{\partial^2\mathbf{E}}{\partial t^2} = \frac{1}{\varepsilon_0}\nabla\rho+\mu_0\frac{\partial\mathbf J}{\partial t}.\tag{1}$$ I wonder if eqn.##(1)## can be split into the following transverse part $$\nabla^2\mathbf{E}_T-\frac{1}{c^2}\frac{\partial^2\mathbf{E}_T}{\partial t^2} = \mu_0\frac{\partial\mathbf{J}_T}{\partial t}\tag{2}$$ and longitudinal part...
