A closed thermodynamic system is one in which
Option (A)
There is no energy or mass transfer across the boundary
Option (B)
There is no mass transfer, but mass transfer exists
There is no energy transfer, but mass transfer exists
Both energy and mass transfer take place across the boundary, but the mass transfer is controlled by values
Correct Option:
Question Solution:
A closed system (also known control mass) consist of fixed amount of mass and no mass can cross its boundary but energy in the from of heat and work can cross the boundary and the volume of closed system does not have to be fixed if energy is not allowed to cross the boundary that system is called isolated system
