Question

Which equation is an expression of the second law of thermodynamics for a spontaneous process?.

Answer 1

The second law of thermodynamics states that a spontaneous process increases the entropy of the universe, S(univ) > 0. If ΔS(univ) < 0, the process is nonspontaneous, and if ΔS(univ) = 0, the system is at equilibrium

What is thermodynamics ?

The science of thermodynamics examines the connections between heat, work, temperature, and energy. The rules of thermodynamics explain how energy moves inside a system and whether or not the system is capable of performing beneficial work on its surroundings.

• Energy cannot be generated or destroyed, according to Thermodynamics' First Law. The entropy of the cosmos increases for spontaneous processes, according to the second law of thermodynamics. Third Law of Thermodynamics: Entropy is zero in a flawless crystal at absolute zero Kelvin.
