NEET Physics Thermodynamics Questions Solved

NEET - 2014

A thermodynamic system undergoes cyclic process ABCDA as shown in figure. The work done by the system in the cycle is



(a) ρoV

(b) 2ρoVo

(c) ρoVo/2

(d)zero

Work done in the cyclic process = Area bound by the closed configuration =Area of closed configuration

={2 [1/2 (Vo/2) x ρo]} + {-2[1/2(Vo/2)ρo]}

=zero
