No mass transfer
A closed system consists of a fixed amount of mass and no mass may cross the system boundary. The closed system boundary may move.
Examples of closed systems are sealed tanks and piston cylinder devices (note the volume does not have to be fixed). However, energy in the form of heat and work may cross the boundaries of a closed system.
