In science, a law is a statement or mathematical relation that concisely describes reproducible experimental observations. Classical thermodynamics is built on a foundation of three laws, none of which can be derived from principles that are any more fundamental. This chapter discusses theoretical aspects of the first law; gives examples of reversible and irreversible processes and the heat and work that occur in them; and introduces the extensive state function heat capacity.
