ANSWER:

Solution 130HP

Part (a)

Step 1 of 6:

We are going to find the change in the internal energy of Carbon dioxide gas for constant specific heat found in the table A.5.

The temperature T1 = 600 K

The temperature T2 = 1200 K

The value of specific heat at constant volume from the table (Cv0) = 0.653 kJ/kg.K

The change in the internal energy is given by

Inserting the values

The change in the internal energy is 391.8 kJ/kg.K.
