The link before the last, is a web page describing the differences between ideal and real gasses. I agree with it. It was posted here for people to read...

Goofy,

How much work are you going to get out of liquid helium at 200 bars and 10 K?

Speaking adiabatically, of course.

Whoa! Guys, those are some pretty harsh words. Tom, you've ask for proof that your theory is wrong. We're attempting to do so. It's understandable that stubbornness on both sides leads to frustration. You've asked me to do a number of searches. Unfortunately for me this is frustratingly getting pret...

I'm still waiting for your hypothesis to start explaining something. So far no hypothesis. Perhaps 200 years of predicting, building successful engines, refrigerators, heat pumps, such as the Ericsson, Malone, Stirling, Phillips, Ryder, ST-5, free position, LTDS's all by engineers using classical th...

If the kinetic energy of both molecules, relative to each other, is high enough, their speed will be above "escape velocity". That means the molecular attraction can be ignored, they are gasses, and they will have positive pressure. Zero contraction is possible. This is why they are called...

Contraction on a PV diagram, by definition, would appear as a negative absolute pressure. A value lower than a perfect vacuum. All those links are in the positive pressure segment of a PV diagram, even when below atmospheric pressure. Trying to redefine contraction to any compression that is below a...

Can you show contraction on a PV diagram?

Have you measured contraction on an indicator diagram?

You've measured this "contraction"? Have data showing an internal tensile force? Shown a piston being pulled back when the open end is in space or a vacuum? No sir. You will always see the cork pushed out of a gun in space. Expansion forever no contraction. Do not confuse an atmosphere pus...

MikeB, thanks. I agree totally. Tom, if a horizontal cylinder piston combination at atmospheric temperature and pressure is turned upside down such that the mass of the piston "hangs", the inside working gas will expand pushing the piston outwardly. The gas is outputting work. The atmosphe...

Heat is converted to work at the instant a gas particle impacts the piston and transfers energy to the piston. Internal energy is like a bank account. Pay-Joules/money coming in is like heat. Your balance-Jouels/money saved is like internal energy, in that they are not the same. Internal energy is ...

Harmonic motion is the kinematic engineering term for a motion that purely sinusoidal in time. Since a crank pin describes a circle anything hooked to it will move, more or less, sinusoidally. A sine wave in kinematics is desirable because it's derivative is a cosine, and the derivative of a cosine ...

Work is depicted on a PV diagram by the bases of Work = F•d, Force times distance. Where pressure is the force and change in volume is the distance. For every pebble removed by rolling it off onto a hill, of the same height preserving their potential energy, the rest of the pebbles are lifted higher...

You seem to accept isothermal lines on a PV diagram? No temperature represented, yet you seem to accept them.

What other lines do you accept?
Constant pressure, horizontal?
Constant volume, vertical?
Adiabatic lines, similar but steeper to the isotherms.
