Partition separates two gases in a rigid well-insulated container. Q=0, W=0.

State 1:

Air:

m=1kg

P=500kPa

T=350K

CO_2:

m=3kg

P=200kPa

T=450K

Assume constant specific heats. Assume kinetic and potential energy changes are negligible. Assume the partition between the two gases can transfer heat between each other and the partition cannot hold any energy itself. Assume both behave as ideal gases.

My question is what equation/table do I use to find out what the specific heats of air and CO_2 actually are?

I appreciate any help.

EDIT: Find the final temp using the first law:

Q-W=m(u2-u1)

Q=0

W=0

U2-U1=0
