Polytropic processes for an ideal gas

[@scottfree6479]

Why couldn’t my professor just explain it like this?

[@alejandrorios9598]

Thanks a lot. your videos are helping me get through this class. I dont know why people are disliking some of videos.

[@halaanbar-ko1ez]

great explanation , thankyou

[@oliviaskipper5335]

Great; clear and concise. Thank you!

[@ggxsky4811]

Can We conserve total mass in a curve applying this relationship

[@earlgarcia1664]

Ughh perfect, many thanks!

[@jacobjames319]

Oh thank you soo much I really appreciated the video it helped me a lot

[@deadawake123]

But how do you found "n" in respect to P and T?

[@encoreman987]

this is great

[@abbas.awmyi0401]

what is the difference between ideal gas and polytropic process?

[@jehoshaphatsiame7525]

Explain polytropic gas

[@TheSunshineRequiem]

why is it must be the same for initial state and final state? 1:17

[@seanoneill6190]

If pV=mRT is true at all times, then the ratio pV/mRT=1 at all times. Therefore, that ratio pV/mRT must be equal (and =1) for the initial and final states.

PV=nRT not mRT ?

[@brentchenoweth]

Both are correct, but the R gas constants will be different values and have different units. When using PV=nRT, R will have units of energy/mol-temp. When using PV=mRT, R will have units of energy/mass-temp. If you are given the number of moles of a gas, PV=nRT makes more sense. If you are given a known mass of a gas, PV=mRT is more useful. Great video by the way!
