Heat and Thermodynamics
Advances in our understanding of energy in the 19th century altered the course of science and society. Foremost among these advances was the understanding of heat as the spontaneous flow of energy from one object to another, caused by a difference in temperature between the objects. Thermodynamics (from the Greek therme, meaning "heat" and dynamis, meaning "power") is the study of energy conversion between heat and mechanical work. Thermodynamics developed out of need to increase the efficiency of early steam engines such as those developed by James Watt.
