NEET Physics Isothermal & Adiabatic Processes MCQ Question
Which of the following combinations accurately describe isothermal and adiabatic processes?
In an isothermal process, temperature remains constant, while in an adiabatic process, no heat is exchanged.
An isothermal process allows for heat transfer, whereas an adiabatic process occurs without any work done on the system.
Both isothermal and adiabatic processes involve constant pressure conditions.
Isothermal processes result in a change in internal energy, while adiabatic processes do not change internal energy.
Correct Answer
Detailed Explanation
Statement A is correct as isothermal processes maintain constant temperature, and adiabatic processes involve no heat transfer between the system and surroundings. Statement B is incorrect because an isothermal process allows heat transfer. Statement C is wrong since isothermal and adiabatic processes do not necessarily involve constant pressure. Statement D is misleading because internal energy can change in an adiabatic process due to work done on the system.
