Hard· Thermodynamic Processes (Adiabatic Process)· +4 / −1
An ideal gas undergoes four different processes from the same initial state as shown in the figure below. Those processes are adiabatic, isothermal, isobaric and isochoric. The curve which represents the adiabatic process among 1, 2, 3 and 4 is:
(Figure: a - diagram with four curves labelled 1, 2, 3 and 4 all starting from the same initial point; curve 4 is the steepest falling curve, curve 1 is the least steep, with curves 2 and 3 of intermediate steepness, consistent with the four standard processes drawn from one common state.)
