Match the thermodynamic processes in List I with their defining physical characteristics in List II and select the correct matching code: List I (Thermodynamic Process) 1. Adiabatic Process 2. Isothermal Process 3. Isochoric Process 4. Isobaric Process List II (Physical Characteristic) 1. Constant volume with zero work done 2. Constant pressure with heat transfer changing enthalpy 3. Constant temperature with internal energy remaining unchanged for ideal gases 4. Constant entropy with no heat exchange with the surroundings

💡 Solution & Explanation

An adiabatic process occurs without any heat transfer between the system and surroundings, keeping entropy constant. An isothermal process takes place at constant temperature, meaning internal energy of an ideal gas remains constant. An isochoric process occurs at constant volume, resulting in zero work done since volume displacement is zero. An isobaric process occurs at constant pressure, where supplied heat alters both internal energy and enthalpy. The first law of thermodynamics governs all these energy transformations.
