PPT-Thermodynamics

branch of physics concerned with the study of both thermal and mechanical or dynamical concepts Application Steam Engines in 1800s Adiabatic Example When a particular piston is released it expands adiabatically lifting a weight The internal energy goes down 10 J How high was the weight lifted. 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.
