Que: Which one of the following represents open thermodynamic system?
A) manual ice cream freezer.
B) centrifugal pump.
C) pressure cooker.
D) bomb calorimeter.
Ans: B
Explanation: as we know in open thermodynamic system heat and mass across the boundary so in centrifugal pump both are acrosed when other option A. Ice cream freezer. C. Pressure cooker and D. Bomb calorimeter no mass are transfered, so ans is centrifugal pump.
