The $\mathrm{P}-\mathrm{V}$ graph of an ideal gas, cycle is shown. The adiabatic process is described by the region
AB and BC
AB and CD
AD and BC
BC and CD
Solution
The adiabatic curve is steeper (has a greater slope).This steepness reflects the rapid change in pressure with volume during an adiabatic process, due to the absence of heat transfer which allows the gas to expand or contract more quaickly in response to changes in volume.
In the given $\mathrm{P}-\mathrm{V}$ graph, adiabatic process is shown by region $A D$ and $B C$ only as their slope is greater.
