पर्याय

• P₀V₀ 

• 2P₀V₀

• `("P"_0"V"_0)/2`

• zero

Answer 1

A thermodynamic system undergoes cyclic process ABCDA as shown in the figure. The work done by the system is `underline(("P"_0"V"_0)/2)`.

Explanation:

Considering anticlockwise sense of the area,

W_BCOB = - Area of triangle BCO = `-("P"_0"V"_0)/2`

Considering clockwise sense of area,

W_AODA = Area of triangle AOD = `("P"_0"V"_0)/2`

∴ Total work = 0
