For the following statements, choose the word or words inside the parentheses that serve to make a correct statement. Each statement has at least one and may have more than one correct answer. a. . According to the Second Law of Thermodynamics, a spontaneous process, such as a balloon filled with hot gas cooling to the surroundings at constant pressure, will always occur (adiabatically, reversibly, irreversibly, without work done).b. . Associated with such a process, there is always an increase in entropy of (the system, the surroundings, the system plus the surroundings, none of these).c. For the example given, the heat gained by the surroundings is just equal to the negative of the (internal energy change, enthalpy change, entropy change, Gibbs free- energy change) of the system. d. To return a system to its initial state requires from the surroundings a change of entropy whose magnitude is (greater than, equal to, less than) that which is gained during the spontaneous process.
