Statement-I: Monoatomic, diatomic and polyatomic gases are adiabatically compressed such that compression ratio is . Then monoatomic gas will have maximum final volume out of these three gases.
Statement-II: Monoatomic gas has least degree of freedom.
Statement-II: Monoatomic gas has least degree of freedom.
View answer and explanation
Correct option: A
Statement-I is true and statement-II is true
Statement-I is true because monoatomic gases have the highest adiabatic index, leading to the smallest volume change during adiabatic compression. Statement-II is true because monoatomic gases have the fewest degrees of freedom (3).
