QUESTION1.

For gaseous carbon dioxide CO2, the number of degrees of freedom of molecules at room temperature (T-294 K)

can be assumed to be f=7. It is assumed that under the selected conditions carbon dioxide can be well described

by the equation of state of an ideal gas. When there is 1040g of gas, calculate

a) Internal energy Eint=

b) Enthalpy H-Eint+pV=

c) isochoric and isobaric heat capacity, Cv and Cp

Cv=

Cp=

adiabatic constant y=
