Isochoric Process Thermodynamics - Work, Heat & Internal Energy, PV Diagrams

This physics video tutorial provides a basic introduction into isochoric process. it explains how to determine the work performed by a gas in an isovolumetric process and how to calculate the heat energy absorbed and the change in the internal energy of a diatomic gas. This thermodynamics video includes the PV diagram for an isochoric process as well a one example problem with multiple parts.

Thanks alot,you have no idea how many lifes you are saving.

[@Patricia-qj3ng]

Hello, did you know whether the deltaU= Q- W is valid in solving the change in internal energy in isochoric or not?

[@the_random_tree_7521]

This guy is such a life saver I have this physics exam and his videos helped me soo much

7:35 summary

[@musarapio_hha]

this formules aplies to the otto cycle?, and how much moles are in the combustion when the piston is at TDC

[@gloriakiptum1781]

Thank you

[@mystkazuo3730]

how we know Cv and Cp ??

[@winproduction7585]

Thank you sir

[@edwardmartin6951]

Cv of water vapor will be 7/2?

[@siyakubongafortune5470]

Yes because water vapour [H2O](g)is a polyatomic gas

[@edwardmartin6951]

@@siyakubongafortune5470 noted with thanks

[@MRPANDA-vh3xf]

How do we find Cv if we dont know if its monoatomic diatomic etc

[@maheshchand7052]

Hi

[@pa1275]

why is R .082

[@nahnahnah30]

Units! There's 0.08206 L·atm/K·mol and 8.314 J/K·mol. In the PV=nRT formula you use the 0.08206 L·atm/K·mol and the units will cancel to leave you with what you're solving for. In this case T so you'll be left with K. Try the formula with the units and cancel them out. pretty helpful trick i think

[@MRPANDA-vh3xf]

@@nahnahnah30 are there other units of R other than that? Like to english units like btu and rankine

[@Patricia-qj3ng]

​​@@nahnahnah30n solving the internal energy using
Cv = 5/2 (R), should it always be 8.3145, will it not affect the equation even if the givens are in Liters and atm? Thank you in advance for ur reply

[@yanbingzhu4650]

Isn’t R ideal gas constant and the value is 8.31 J/(molxK)?

[@nickoemmanuelvillacruz3090]

It depends on the units of pressure Temperature

[@nickoemmanuelvillacruz3090]

Pressure volume temperature

[@captainsincers7289]

Depends on the unit is 8.31 for Pa and m^3 however when working with litres ant atm(atmospheric pressure) we use 0.08206

[@Christiano-l1r]

He should have used 0.08206 as R since the pressure is at ATM and Volume is in Litres ....R is always 8.3145J when the pressure is in Pascal and volume is in Cm³

[@zoereed4010]

Cv is 3/2 not 5/2. That is Cp for isobaric

[@katlegomathiane3759]

Zoe Reed it’s 5/2 for a diatomic gas 3/2 for a monoatomic
