NEET Physics Isothermal & Adiabatic Processes MCQ Question
Consider a diagram of a piston-cylinder assembly undergoing an adiabatic process, where the piston compresses the gas. Which of the following correctly describes the work done on the system during this process?
Work is positive because the system's volume decreases.
Work is negative because the system's pressure decreases.
Work is zero because there is no heat transfer.
Work is undefined because the temperature remains constant.
Correct Answer
Detailed Explanation
In an adiabatic process, work done on the system during compression is positive since the volume decreases, as described in the context with p_ex and ΔV.
