Adiabatic process

“Is there a thermodynamic process with no heat exchange?”
When most people think of thermodynamics, one of the first thing that pops into people’s minds is one phenomenon, heat flow. However, is it possible to have such a process with no heat flow? Well, let’s think about it. If we were to take our system and completely isolated it inside an insulator, no heat would be able to flow in or out. Therefore, all of the work done must come from the internal energy. This phenomenon is known an adiabatic process. In an adiabatic process, the pressure multiplied by the volume raised to the ratio of the specific heats of the gas is always equal to a constant (PV^(c_p/c_v)), leading to a steeper PV diagram than the isothermal process.
