Terminologies in Chemical Thermodynamics Review Questions with complete Solutions Graded A+

First Law of Thermodynamics - Answers Energy cannot be created or destroyed.

Total Energy - Answers Constant energy of the universe.

Energy Conversion - Answers Energy can change forms or transfer.

Spontaneous Processes - Answers Processes proceeding without outside intervention.

Nonspontaneous Processes - Answers Reverse processes that do not occur spontaneously.

Temperature Dependence - Answers Spontaneity can change with temperature.

Reversible Processes - Answers Processes that can be reversed exactly.

Irreversible Processes - Answers Processes that cannot be undone exactly.

Entropy (S) - Answers Measure of randomness in a system.

Clausius' Contribution - Answers Defined entropy related to heat and temperature.

State Function - Answers Property dependent only on current state.

Entropy Change Formula - Answers ΔS = Sfinal − Sinitial.

Isothermal Process - Answers Process at constant temperature.

Second Law of Thermodynamics - Answers Entropy of the universe increases in spontaneous processes.

Microstate - Answers Specific arrangement of molecules in a system.

Boltzmann Constant (k) - Answers k = 1.38 × 10⁻²³ J/K.

Entropy Equation - Answers S = k lnW, where W is microstates.

Molecular Motion Types - Answers Translational, vibrational, and rotational motions.

Entropy and Temperature - Answers Higher temperature increases entropy.

Entropy and Volume - Answers Larger volume increases entropy in gases.

Entropy and Physical States - Answers S(g) > S(l) > S(s) indicates entropy order.

Dissolution of Solids - Answers Ions generally have higher entropy.

Third Law of Thermodynamics - Answers Entropy of pure crystalline substance at absolute zero is 0.

Standard Entropies - Answers Molar entropy values in standard states.
