### Dependence on $(p,V,T)$ rather confusing

I am currently taking the freshman thermodynamics course and have asked several times for explanations of the relationships which can, and which cannot, and why they cannot. But I still don't really ...

### Does this theorem holds out for spacetime?

The theorem: Let $F$ and $C$ be two finite geometric figures (those defined by two continuous functions in a given region $D$), where $F$ belongs to an $n$-dimensional Euclidean space and $C$ is the ...

### Haag’s theorem in finite volume

I’ve been reading on Haag’s theorem and found this proof that uses standard QFT instead of the axiomatic kind: https://arxiv.org/abs/2011.08875 It essentially boils down to saying that the vacuum ...

### Area of a $pV$ diagram [duplicate]

On a $pV$ graph (where the Pressure is on the Y axis, and the Volume is on the X axis), I am conceptually confused on how the area under the graph is equivalent to the work done by the system (...

### How does Pressure times Volume = Work Done?

I understand the equation mathematically-- $p$ times (change in) $V$ = Work done. However, I am confused about it conceptually. Work is (in a non-calculus context) constant force applied over a set ...
### Confusion on $pV$ diagrams
I am extremely confused on the concept of a $pV$ diagram. I understand that Pressure times (change in) Volume equals the Work done by a piston; however, I am confused on how volume and pressure can ...
