One mole of `CO_(2)` at 300 K and1 atm pressure is heated in a closed vessel so that temperature is 500 K is pressure is 5 atm. Then it is cooled so that temperature is 300 K and pressure is 1 atm. What is the change in internal energy of the gas ?

To find the change in internal energy (\( \Delta U \)) of one mole of \( CO_2 \) gas during the described process, we can use the following steps: ### Step 1: Understand the process We have one mole of \( CO_2 \) gas that undergoes two main changes: 1. Heating from 300 K to 500 K at constant volume (since it's in a closed vessel). 2. Cooling back to 300 K at constant pressure (1 atm). ### Step 2: Use the formula for change in internal energy ...
