Thermodynamic Work

AI Thread Summary

To find thermodynamic work when pressure (P), volume (V), and temperature (T) are not constants, express P as a function of V. If the derivative dp/dv is constant, it simplifies the process. The work done can then be calculated using the integral W = ∫ P dV. This approach allows for the evaluation of work under varying conditions. Understanding these relationships is crucial for accurate thermodynamic calculations.

Hi,

How can I find the thermodynamic work from
dw=Pdv

if P, Vand T are not constants?
what if I knew that dp/dv is a constant in this case?

You need to express P as a function of V first. Then you can evaluate the integral,

W = ∫ P dV

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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
