Thermodynamics and P-V Diagrams

085 - Thermodynamics and P-V Diagrams

In this video Paul Andersen explains how the First Law of Thermodynamics applies to an ideal gas in a piston. A pressure-volume graph can be used to determine the type of thermodynamic process. Included is a discussion of and P-V diagram for isothermal, isovolumetric, isobaric, and adiabatic process.

Thanks. Having to go to class to learn this is very annoying if you professor isn't good. You've saved me much time.

Mr Anderson I really enjoy your videos. You are a great teacher, sir.

[urwaimran]

Yes that was helpful. You are the best teacher ever.

[RogueNiNja]

Mr AndersonThe units in the PV graph are wrong the unit of pressure is pascal and volume has meter cube at 3.56 .Thank you for this helpful videoRegards

[archerdev]

Excellent explanation. Physics bless you sir, Thank you.

Brilliant video. A quick correction for the example you gave at 1:20. This is an isothermal compression, therefore the work done by the surroundings on the system actually causes heat to exit the system, NOT a change in the internal energy. The internal energy stays constant (0 = Q + W hence -Q = W)

It is one of the best videos on that topic, thanks ❤

[roopalagarwal]

For the first time I could understand it well! Thanks a lot...

[ezanagebregziabher]

all explanations except isobaric are satisfying.

[floriskleinestaarman]

I am sorry I say this, but I think you made a mistake in your explanation about internal energy. I have learned that heat is equal to internal energy (dU) + work (dW). So this means instead of dU=Q+W the formula must be dU=Q-W, because of the formula: Q=dU+dW ofcourse. But I could be wrong about this....

which software you are used for making pv diagram and other graph?

please give me name of the software

[Astralintroverted]

saved me from confusion! simple n effective..

[anilsharma-evmy]

I pressed an empty closed cold drink 🍼 bottle so how i know work done by me
2 liter empty bottle closed and pressed by me so how i know work done by me ?

Pressure and volume of close bottle are changing but where the volume increased if bottle is closed ??

[JatinUppal]

the slope of polytropic process will be more or less steeper than adiabatic process??

[jacobmoje]

hello.... please add a video calculating "workdone" at the moving boundary of a simple compressible system.

[anilsharma-evmy]

What is total work done by atmospheric pressure at globe level ???

[Abdulrahman-woob]

Can you explain "polytropic" process, and is it related to "isentropic" process

[haseebh]

What software are you using for making the graphs

[mahalakshmikaki]

How is more work is done by the isothermal than adiabatic

[natubhaidave]

Unit of pressure and volume are exchanged in graph in this video
