What's wrong with this

[tinman]

My understanding of what Tinman is saying is that he does need external energy to condense the gas to liquid.  If one has a heat sink below the phase change temperature for the pressure one is at, then simply cooling the gas and in the process giving up stored energy to the heat sink will condense the gas to liquid.

No
Energy is needed to turn the liquid into gas-this I have said many times already. Energy is returned when the gas is converted back to liquid.
Mark-what is mass?

I see. We need to present him to the Nobel Prize.   For the courage of presenting new theories.

What about Oxygen-gas (for example) turning into liquid?

We agree that it takes energy to convert material from liquid phase to gas phase.  We agree that gas can be converted to liquid by removing heat.  We agree that heat can be removed without adding energy when one has a heat sink that is below the phase change temperature for the pressure.

I answered you on mass a couple of posts back.  It is a property of matter.  That property establishes both resistance to acceleration (inertia) and force attributable to acceleration towards other masses commonly referred to as gravitational force.

So do you agree that a stationary objects mass here on earth is its weight?
Next-and this is important, so answer carfully. Dose electrical power have mass-eg, volts, current
