Question

The area under a p-V graph for an adiabatie processis qual to the heat transfer. a)True b) False

Answer 1

Answer:

false

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.
