Heat transfer processes convection conduction radiation Physics of the atmosphere the ozone layer Greenhouse effect climate change 1 Thermodynamics review Thermodynamics is the science dealing with heat work and energy and the transformation of one into the other. 1. st. law of thermodynamics. Energy may be converted to different forms, but it is neither created nor destroyed during transformations. Energy from chemical bonds is converted to kinetic energy and heat (body and friction from tires). Thermodynamics. Rub your hands together for 15 seconds.. Are your hands warm?. Thermal energy. Thermodynamics. The study of the effects of work, heat flow, and energy on a system. Movement of thermal energy. No engine, working in a continuous cycle, can take heat from a reservoir at a single temperature and convert that heat completely to work.. Therefore, no engine can have a greater efficiency than a Carnot engine operating between the same two temperatures.. [4]. Change of phase . . ice. .  . water.  . steam. The Laws of Thermodynamics.
