(A): Air in a cylinder is suddenly compressed by a piston. If the volume after compression is half the original volume the final pressure is twice the initial pressure.
(R): Suddenly compressed process is isobaric process.
(R): Suddenly compressed process is isobaric process.
View answer and explanation
Correct option: D
Both (A) and (R) are false
Option D (Both (A) and (R) are false) is correct because sudden compression is an adiabatic process, not isobaric, and the final pressure is not simply twice the initial pressure.
