ADerive the equation for the work done w reversibleas a function of the initial and final temperaturesTo understandthe relationship between work and heat we need to understand athird linking factor the change in internal energy Energy cannotbe created nor destroyed but it can be converted or transferredInternal energy refers to the all the energy within a given systemincluding the kinetic energy of molecules and the energy stored inall of the chemical bonds between molecules With the interactionsof heat work and internal energy there are energy transfers andconversions every time a change is made upon a system However nonet energy is created or lost during these transfersDefinition1st Law of ThermodynamicsTheFirst Law of Thermodynamics states that energy can be convertedfrom one form to See Answer
