Vedclass · Answer

(C) Entropy $(S)$ is a measure of the randomness or disorder of a system. $\Delta S$ is positive when the randomness of the system increases. $1$. Mixing of two gases increases the number of possible arrangements of molecules,thus increasing the entropy $(\Delta S > 0)$. $2$. Boiling of a liquid involves the transition from a liquid state to a gaseous state,where molecules have much more freedom of movement and disorder,thus increasing the entropy $(\Delta S > 0)$. Therefore,both processes lead to an increase in entropy.

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