It has been confirmed that rotation around the carbon-carbon bonds is one of the fastest processes in chemical and process engineering, It was also confirmed that all matter has the ability and possess enough energy to vaporise in a split second, but they are being constrained by their strain energies. In this research work, the strain energy of L.N.G. was configured in a manner that depicts molecular quantization. Atume's series was used to determine energy absorbed and energy possessed by n-alkane molecules. In branched chain alkanes, Newtonian mechanics was applied to obtain the kinematics of a second order differential equation and it was connected with the dynamics of ebullition. That is, keeping the position of the n^th carbon atom constant and varies the momentum of ebullition. Branched chain alkanes obeyed the Heisenberg uncertainty principle and their wave functions satisfied the first postulate of quantum mechanics through a probabilistic interpretation of the sinusoidal wave function ("psi"). Finally, the isothermal Gibbs-Atume equations were derived for gases, solids and liquids with their applications in petroleum analysis and strain energy minimization.
