    Isothermal Process
AI Thread Summary
The discussion revolves around solving a problem involving a monoatomic ideal gas undergoing an isothermal process with constant pressure and volume. The user understands that the total work equals the total heat, indicating no change in internal energy due to the initial and final temperatures being the same. They seek assistance in calculating the heat supplied during two specific segments of the process without receiving direct answers to promote learning. The user is also curious about the state variables that affect the ideal gas. Overall, the focus is on understanding the principles of thermodynamics related to isothermal processes.

Homework Statement


I have a diagram of a process of a monoatomic gas.


and the problem is that I know that the total amount of work = total amount of heat,
so there is no internal energy change. why? because my process started at the same temp that it finished. how ever... it is asking me the heat supplied from 1--->2 when they kept constant pressure, and 2----->4 when they kept constant volume

Homework Equations



W = nRT ln V2/V1

The Attempt at a Solution



please help me with this but do not give me the answer otherwise i won't learn! hehe
thank you!

It is an ideal gas. What are the state variables it depends on?

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
