Repeat Problem 3.134 but use a constant specific heat at the average temperature from the equation in Table A.6 and also integrate the equation in Table A.6 to get the change in enthalpy.

Data from Problem 3.134

For a special application, we need to evaluate the change in enthalpy for carbon dioxide from 30◦C to 1500◦C at 100 kPa. Do this using the constant specific heat value from Table A.5 and repeat using Table A.8. Which table is more accurate?
