Energy can be converted from one form to another but energy cannot be created or destroyed. (E.univ = 0) - 1st Law of Thermodynamics (E.univ = 0) The entropy of the universe increases in a spontaneous process. Spontaneous process ( S.univ = S.sys + S.surr ) - 2nd Law of Thermodynamics (S.univ > 0) The entropy of a perfect crystalline substance is zero at the absolute zero of temperature, (-273 C = 0 K). This law enables the determination of the absolute antropies of substances - 3rd ...
