New Physics Video Playlist - Otto Cycle of Internal Combustion Engines, Gamma vs Compression Ratio, Adiabatic Processes - Physics

This physics video tutorial provides a basic introduction into the otto cycle of an internal combustion engine. The first step is an adiabatic process when the gas undergoes compression. As the volume decreases, the temperature of the gas increases and the pressure greatly increases favoring ignition. The second step is an isochoric process which causes a further increase in pressure. Heat is added in this step but no work is done. The third step is an adiabatic expansion - no heat is transferred but the gas performs work on the surroundings as it expands. The final step is an isochoric process where the pressure decreases. This video also contains a few practice problems on calculating the compression ratio, the gamma ratio, and the efficiency of the internal combustion engine as well as the molar heat capacity of the working substance at constant volume and at constant pressure. This thermodynamics video tutorial contains plenty of examples and practice problems.
