The shape of T-S diagram for Carnot Cycle is a

A. Rectangle

B. Rhombus

C. Trapezoid

D. Circle

Answer: Option A

Solution(By Examveda Team)

The Carnot cycle consists of
$$1.$$ Reversible isothermal expansion so, \[T = {\rm{CONSTANT}}\]
$$2.$$ Reversible adiabatic expansion so, \[S\left( {{\rm{entropy}}} \right) = {\rm{CONSTANT}}\]
$$3.$$ Reversible isothermal compression so, \[T = {\rm{CONSTANT}}\]
$$4.$$ Reversible adiabatic compression so, \[S\left( {{\rm{entropy}}} \right) = {\rm{CONSTANT}}\]
