Chestermiller replied to the thread Expansion or compression -- which is more energy efficient?.There is no net work done on the piston, and, thus, no net energy "spent by the piston." I show this below. From Newton's 2nd law of... -
Chestermiller replied to the thread Expansion or compression -- which is more energy efficient?.I totally disagree with your interpretation and stand by what I said previously. You should know that I have a lot of practical...

Chestermiller replied to the thread Expansion or compression -- which is more energy efficient?.Yes. If you are pulling the piston outward, the net work is equal to the work to push back the atmosphere plus the work done to pull on...

Chestermiller replied to the thread Expansion or compression -- which is more energy efficient?.In Post #17, I calculated the change in internal energy U in scenario 1. In this post, I will should that this matches the work done by...

Chestermiller replied to the thread Expansion or compression -- which is more energy efficient?.sorry;. If R=2 calories/mole-K, then 2.5R= 5 calories/mole-K. In our case,, R=8.314 Joules/mole-K, and 2.5 R = (2.5)(8.314)...

Chestermiller replied to the thread Expansion or compression -- which is more energy efficient?.A pressure of 1 kg/cm^2 corresponds to ##0.98\times10^5\ Pa## pressure. From the ideal gas law, for 1 mole gas at 300 K, the ideal gas...

Chestermiller reacted to haruspex's post in the thread If Heat Is Motion, Why Isn’t All Motion Heat? with
Like.
Is that the exact wording of the question? I ask because in scientific usage "heat" only refers to the transfer of energy between...
