Thermodynamics is the study of the relationship between heat and work. The first law of thermodynamics is merely a quantitative expression of the principle of conservation of energy. This means that you cannot get more energy out of a system than the total energy that went into the system. Since all materials have energy associated with them, mass as well as energy must be taken into account. This law is of importance where transfer of mass or energy is involved.
