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.
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!
Why couldn’t my professor just explain it like this?
Thanks a lot. your videos are helping me get through this class. I dont know why people are disliking some of videos.
But how do you found "n" in respect to P and T?
Ughh perfect, many thanks!
Great; clear and concise. Thank you!
Oh thank you soo much I really appreciated the video it helped me a lot
Can We conserve total mass in a curve applying this relationship
great explanation , thankyou
Life saver 🙏🏾
what is the difference between ideal gas and polytropic process?
this is great
why is it must be the same for initial state and final state? 1:17

Grgreat work
Explain polytropic gas
PV=nRT not mRT ?
