What is Thermodynamics? b Thermodynamics comes from the Greek: b “therme” B heat b “dynamis” B power b Orginally motivated by the need to convert heat to work (i.e., the need to analyze engines) b More generally, thermodynamics deals with conversion of one form of energy to a different form of energy (e.g., work, heat, kinetic energy, potential energy, internal energy)

What is Thermodynamics? b Apply thermodynamics to study: b Engines b Power plants b Air-conditioners b Refrigerators b Heat pumps b Thermal systems b Thermodynamics can be used to reduce energy consumption, operating costs, and environmental impact of equipment

What is Thermodynamics? Two important laws of thermodynamics: b 1 st Law: Energy can never be created or destroyed, it just changes its form Example 1: Reference PE = 7 units KE = 3 units PE = 0 units KE = 0 units PE = 10 units KE = 0 units
