AI Thread Summary
Heat presence does not negate the solidity of matter; instead, it causes molecular movement, typically in the form of vibrations within a fixed position. Solids can exist at various temperatures above absolute zero, where molecular motion is limited but still present. The misconception arises from equating heat-induced movement with disordered motion, rather than recognizing it as vibrational energy. Therefore, solids do not need to remain at 0 K to exist; they simply exhibit different states of molecular activity at varying temperatures. Understanding this distinction clarifies the relationship between heat, movement, and the solidity of matter.

Noobie question...

Where there is Heat there is movement, so does that mean that whenever heat is present matter cannot be solid?

If that is true, all solid must stay at 0 K. How correct do you think this is?

I'm not getting the concept then. Or maybe is it correct to say that solids will tend to be closer to 0K? Because if in Heat there is movement means that molecules or atoms are tightly packed, or am I mixing terms up?
 
The problem here is that you think movement mean things are going off all over the place. How about movement as in just vibration about a fixed position?

Got it! Thank you for the clarification.

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...
