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

Cv of water vapor will be 7/2?
@siyakubongafortune54702 жыл бұрын
Yes because water vapour [H2O](g)is a polyatomic gas

why is R .082
@nahnahnah305 жыл бұрын
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

@@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

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

It depends on the units of pressure Temperature

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 Жыл бұрын
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

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

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