Impossible thermodynamics Q :(((

In summary, impossible thermodynamics is a theoretical branch of thermodynamics that explores systems that are impossible or violate the laws of thermodynamics. It differs from traditional thermodynamics in that it deals with hypothetical systems rather than real-world ones. It cannot be applied in real-world scenarios, but it helps expand our understanding of thermodynamics and can lead to new discoveries. Examples of impossible thermodynamic systems include perpetual motion machines and systems that violate the second law of thermodynamics. Studying impossible thermodynamics benefits the field by deepening our understanding and stimulating further research and innovation.

Homework Statement
My professor has made up this question for us and I have no idea what I’m doing. I drew a diagram but I don’t know how to answer these questions

Consider a cylinder with a fixed piston, Half-way up the cylinder is a thin sheet of glass, separating the cylinder in to two halves.
N particles of gas exist on one side (A) of the partition, and 0(zero) particles on the other (B). At t=0, the glass plate shatters into tiny pieces (essentially ‘disappears’), & The gas in A can expand into side-B. a) is there any (moving) boundary for the gas to push against? Can any work be done? W=Integral(F * dX) b) what does the f(v) function of the gas as it passes by a plane close to the (shattered) glass plate look like (compare/contrast to the f(v) from side A before the glass broke.) c) in this ‘nearly instantaneous’ change, can heat flow from the cylinder into the gas? d) write out the numerical values of the terms in the 1st-law as a result of a)-c)

Any help is greatly appreciated :)

If the volume of the container is fixed, can any work be done on the surroundings? Or on the flip side, on the system?

For thermodynamics it's often easier to consider the pressure-volume form for work done on the system, namely ##W = -\int_{V_1}^{V_2} P dV##.

1. Can impossible thermodynamics be applied in real-world scenarios?

Impossible thermodynamics is a theoretical concept that explores the limits of thermodynamic systems. While it may not have direct practical applications, it can help scientists better understand the laws of thermodynamics and their implications.

2. What makes a thermodynamic process impossible?

A thermodynamic process is considered impossible if it violates the laws of thermodynamics, such as creating perpetual motion or achieving 100% efficiency in energy conversion.

3. How is impossible thermodynamics different from traditional thermodynamics?

Traditional thermodynamics deals with real-world systems and processes, while impossible thermodynamics explores the theoretical limits of these systems. It also introduces the concept of negative temperatures, which are impossible to achieve in traditional thermodynamics.

4. What is the significance of studying impossible thermodynamics?

Studying impossible thermodynamics helps scientists gain a deeper understanding of the fundamental laws of thermodynamics and their implications. It also allows for the exploration of extreme scenarios and the development of new theories and concepts.

5. Can impossible thermodynamics lead to new technological advancements?

While the direct applications of impossible thermodynamics may be limited, the insights gained from studying it can potentially lead to new technological advancements in areas such as energy storage and conversion, as well as the development of more efficient systems.
