Understanding Adiabatic Processes
An adiabatic process is a thermodynamic process that occurs without any heat transfer to or from the system. Let's break down the statements provided to clarify why the correct answer is option 'A'.
Statement 1: No transfer of heat between the system and surroundings
- This statement is correct.
- In an adiabatic process, the system is perfectly insulated, ensuring that there is no exchange of heat with the surroundings.
- This is a fundamental characteristic of adiabatic processes, which can occur in various scenarios, such as rapid expansions or compressions of gases.
Statement 2: These processes lead to a decrease in entropy
- This statement is incorrect.
- While adiabatic processes can be reversible or irreversible, the second law of thermodynamics states that the entropy of an isolated system will either increase or remain constant; it cannot decrease.
- In an irreversible adiabatic process, the entropy will increase, while in a reversible adiabatic process, the entropy remains constant.
Conclusion
- Therefore, the first statement is accurate, while the second is not.
- The correct answer to the question is option 'A', as only the first statement about heat transfer is correct.
Understanding these principles is crucial for grasping thermodynamics and its applications in various fields, including physics and engineering.

- An adiabatic process is a process in which there is no transfer of heat between the system and surroundings. Here, the wall separating the system and the surroundings is called the adiabatic wall. The adiabatic process can be either reversible or irreversible.
- The adiabatic lapse rate is the rate at which the temperature of an air parcel changes in response to the compression or expansion associated with elevation change, under the assumption that the process is adiabatic, i.e., no heat exchange occurs between the given air parcel and its surroundings.
- Adiabatic lapse rate: Change of temperature with a change in altitude of an air parcel without gaining or losing any heat to the environment surrounding the parcel.
- Adiabatic processes are characterized by an increase in entropy, or degree of disorder, if they are irreversible and by no change in entropy if they are reversible. Adiabatic processes cannot decrease entropy.
