    Entropy
AI Thread Summary
Entropy is often described as a measure of disorder in a system, while enthalpy represents the heat content of a substance. An analogy for enthalpy is the sensation of burning your hand when touching hot water, illustrating the energy transfer involved. In contrast, entropy can be likened to a chaotic room that becomes messier over time, symbolizing the natural tendency toward disorder. The discussion highlights the need for relatable analogies to help students grasp these complex thermodynamic concepts. Understanding these properties is essential for comprehending energy changes in physical processes.

Iwant any analogy for entropy & enthalpy...
For example quasi static process can be related to "old man with health problem walks almost static"... so students can easily understand. ... can you please suggest any analogy for ENTROPY & ENTHALPY

It's not clear how you want to analogize these two properties. Enthalpy burns your hand if you stick it into a pan of hot water. Who knows what entropy does.
 
Enthalpy h = u+pv, can you please explain burning of hand in terms of h = u, pv ... what are the changes in these terms

All I know is enthalpy = heat content of a substance. Entropy is more theoretical and variously described as a measure of disorder in a system.
 
Thank you for your reply brother.. if you know anything in future kindly let me know...

Thread 'Entropy and configurations of microstates'

I was watching a Khan Academy video on entropy called: Reconciling thermodynamic and state definitions of entropy. So in the video it says: Let's say I have a container. And in that container, I have gas particles and they're bouncing around like gas particles tend to do, creating some pressure on the container of a certain volume. And let's say I have n particles. Now, each of these particles could be in x different states. Now, if each of them can be in x different states, how many total...

Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'

Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...
