Chapter 17 // Second Law of Thermodynamics

This video explains the Second Law of Thermodynamics which states that: In any spontaneous process there is always an increase in the entropy of the universe.
Also it explains the temperature effect on the entropy. The entropy of a substance increases with temperature where the Entropy changes in the surrounding are primarily determined by heat flow (from/to system to/from surrounding)
change in the surrounding entropy = ΔSsurr = - ΔH/(𝑇 (𝐾))
