MHT CET 2024 Physics question
There are two samples A and B of a certain gas, which are initially at the same temperature and pressure. Both are compressed from volume to . Sample A is compressed isothermally while sample B is compressed adiabatically. The final pressure of A is
Answer: (D)
Solution
Let the initial pressure be and volume . Isothermal compression (Boyle's law): , so . Adiabatic compression: , so . Since for any gas, , so , i.e. the final pressure of A is less than that
