Question

An adiabatic process in a thermodynamic system is one in which there is? 
1. Limited heat transfer to or from the system through the boundary
2. No heat transfer to or from the system through the boundary
3. No internal energy change
4. No energy transfer to or from the system through the boundary

Answer 1

Correct Answer - Option 2 : No heat transfer to or from the system through the boundary

Explanation:

• An adiabatic process is a thermodynamic process in which there is no exchange of heat between the system and surroundings, that is, the heat remains constant.
• Hence in the adiabatic process ΔQ = 0 since there is no exchange of heat which means
• In an adiabatic process, energy is transferred only as work.
• ∴ ΔE = ΔW
