Calculating Heat Energy (HELP)
A mixture consisting of 1.00g oxygen gas and 1.00g neon gas is trapped within a 1.0L container at an initial temperature of 298K. Calculate the heat energy required to increase the temperature of this mixture to 398K
(a) at a constant volume of 1.0L
(b) under conditions where the container is allowed to expand against a constant pressure pext. The pressure pext is equal to the initial pressure of the mixture at 298K.
* note: base your calculations on the equipartition theorem. (do not tabulate heat capacity values)
C=q/ΔT
Um(T)=3/2RT (*)
(a) ΔU = qv when volume is constant
When using equipartition theorem (*), what should I put for temperature?
(b) ΔH = qp when pressure is constant.
Should I use formula H = U + pV to calculate ΔH?
Thanks in advance!
