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?
