The word ‘thermodynamics’ implies the flow of heat. It deals with energy changes accompanying all types of physical and chemical
processes. It helps to lay down the criteria for predicting the feasibility or spontaneity of a process, including a chemical reaction, under a
given set of conditions. It also helps to determine the extent to which a process, including a chemical reaction, can proceed before
attainment of equilibrium. Thermodynamics is based on two generalizations called the first and second laws of thermodynamics. These are
based on the human experience.
