In which of the following processes, beat is neither absorbed nor released by a system?
Assertion: Equal volumes of monatomic and polyatomic gases are adiabatically compressed separately to equal compression ratio `("P"_2/"P"_1)`. Then monatomic gas will have greater final volume.
Reason: Among ideal gases, molecules of a monatomic gas have the smallest number of degrees of freedom.
An ideal gas is compressed to half its initial volume by means of several processes. Which of the process results in the maximum work done on the gas?
