Is there a formula of heat that expresses it in microscopic work done?
If I understand correctly looking at the first law of thermodynamics we have a microscopic work term (heat: $Q$) and macroscopic work term ($W$)
$$ \Delta E = \Delta Q + \Delta W$$
The macroscopic work … My question is: is there a way of describing heat as microscopic work? …

What is the differentiating factor between work and heat?'
The key difference between work and heat lies in how they affect the system’s microstates. … Work
When work is done on a system, how the microstates change depends on how the work is applied. …

Understanding the shape of Carnot loop in the $p$-$V$ plane
The area enclosed by a loop is the total work done. If you draw a square, isn't that the maximum amount of work done possible instead. … It seems that an isobaric path gives the most work per area. …

How is the 'lost' work related to the entropy change in free expansion? Why is it not just d...
How exactly is the work 'lost' related to the entropy 'gained'? … = \int_{V_0}^V \frac{nRT}{V} dV = nRT \ln \frac{V}{V_0 }= nRT \ln 2$$
So the energy (work) 'lost' to the universe is for example 300 Joules. …

I am confused about the minus signs in potential and kinetic energies
I'm not using Work because I am using potential energies. I think I should not get a minus sign there for the potential energy of gravity. …

What happens to entropy during compression?
Entropy is a measure of how many microscopic states (or "microstates") a system can occupy. The more possible microstates, the higher the entropy. For a gas, these microstates can be related to both p …
