Answer:
false
Step-by-step explanation:
P-V diagram is the plot between pressure and volume . In adiabatic process heat transfer is zero.
so,
Area under P-V diagram for adiabatic process does not shows the heat transfer where as area under P-V diagram shows the work done by the gas.
As gas expands in adiabatic process positive work is done which leads to decrease in temperature and internal energy.
