(A): In an isolated system the entropy increases. (R ): The process in an isolated system are adiabatic. (2006)

Which correctly represents the entropy (s) of an isolated system during a process.

(A): For a process to be spontaneous, the change in free energy must be negative. (R): The change in entropy for a process must always be positive if it is spontaneous.

For the reaction I_(2(g)) hArr I_(2(s)), Delta H= -ve . Then choose the correct statement from the following (A) The process is spontaneous at all temperature (B) The process is accompained by an increase in entropy (C ) The process is accompained by a decrease in entropy (D) The process is accompained by a decrease in enthalpy

During winters, moisture condenses in the form of dew and can be seen on plant leaves and grass. The entropy of the system in such cases decreases as liquids possess lesser disorder as compared to gases. With reference to the second law, which statement in correct, for the above process?

Consider the following statements and choose the correct answer. a) if heat is added to a system, its temperature must always increase. b) if positive work is done by a system in thermodynamics process, its volume must increase.
