Vedclass · Answer

(C) Entropy $(S)$ is a measure of the randomness or disorder of a system.For a gas,increasing the pressure at a constant temperature decreases the volume,which leads to a decrease in the number of available microstates,thus $\Delta S In option $C$,the pressure of $N_2$ gas increases from $1 	ext{ atm}$ to $8 	ext{ atm}$,which results in a decrease in entropy.Therefore,$\Delta S$ is negative for this process.

In which of the following processes is $\Delta S$ negative?

In which of the following processes does the entropy decrease?

One mole of an ideal diatomic gas $(C_V = 5 \ cal)$ was transformed from initial $25 \ ^{\circ}C$ and $1 \ L$ to the state when temperature is $100 \ ^{\circ}C$ and volume $10 \ L$. The entropy change of the process can be expressed as $(R = 2 \ cal / mol \cdot K)$ :-
