What is the change in internal energy of an ideal gas during an isochoric process?
Correct Answer: Increase in internal energy
- Step 1: Understand what an isochoric process is. It means the volume of the gas does not change.
- Step 2: Know that internal energy is related to the temperature of the gas.
- Step 3: Realize that if heat is added to the gas during an isochoric process, the temperature increases.
- Step 4: Since the temperature increases, the internal energy of the gas also increases.
- Step 5: Conclude that the change in internal energy is equal to the heat added to the gas.
