Purpose (Il) S.J.T.U. Phase Transformation and Applications The science of thermodynamics is concerned with heat and work,and transformations between the two. It is based on two laws of nature,the first and second laws of thermodynamics. By logical reasoning and skillful manipulation of these laws,it is possible to correlate many of the properties of materials and to gain insight into the many chemical and physical changes that materials undergo.
