     Work done in a constant volume process is  zero  negative  positive  none of the above 
  
  Solution
the constant volume process is also called as isochoric process
work done is given by the product of pressure and volume
W= PV
on differentiating
dW = PdV
as it is the constant volume process , change in the volume is 0 , dV=0
therefore, dW = P(0)
dW= 0
so work done in a constant volume process is 0
