AI Thread Summary
For an ideal gas, the relationship between specific enthalpy and specific internal energy is clarified through the equation for specific enthalpy, which includes pressure and specific volume. The discussion highlights that specific enthalpy (h) is defined as specific internal energy (u) plus the product of pressure and specific volume. To derive specific internal energy, one can manipulate the equations involving mass, specific heat capacity, and temperature changes. The assertion that specific enthalpy equals specific internal energy at constant pressure is questioned, indicating a potential misunderstanding. Clarification is needed on the conditions under which this relationship holds true for ideal gases.

I read that for an ideal gas, the specific enthalpy (h) at constant pressure is equal to the specific internal energy of the gas. How do I proof that?

I know that:

1.) specific enthalpy = specific internal energy + pressure x specific volume

2.) Internal energy at constant pressure = mass of gas x capacity x change in tempt. + (pressure x volume of gas)

3.) pressure x specific volume = gas constant x temperature

How do I obtain specific internal energy? Do I simply divide both sides by (m)?

How do I proceed on after I've obtained specific internal energy?

Where did you read this? It doesn't sound right, as written.
 
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...
