Question

(4) Draw P-V diagram for positive work at constant pressure
​

Answer 1

There is a decrease in the pressure of the gas as the volume of the gas increases. The figure shows the corresponding P-V diagram. initial condition, the piston is moved inward extremely slowly so that the gas is compressed. There is an increase in the pressure of the gas as the volume of the gas decreases.

Hope it will helps ✌
