Detailed explanation-1: -Isolated: no matter or energy enters or leaves. Closed: energy enters and leaves but material does not. Open: both energy and matter enter and leave.
Detailed explanation-2: -A closed system is a system that is completely isolated from its environment. This is the definition commonly used in the system literature, which we have chosen to follow.
Detailed explanation-3: -In thermodynamics, a closed system can exchange energy (as heat or work) but not matter, with its surroundings. An isolated system cannot exchange any heat, work, or matter with the surroundings, while an open system can exchange energy and matter.
Detailed explanation-4: -An open system can exchange both energy and matter with its surroundings. The stovetop example would be an open system, because heat and water vapor can be lost to the air. A closed system, on the other hand, can exchange only energy with its surroundings, not matter.
Detailed explanation-5: -Open, Closed, and Isolated Systems A closed system does not allow matter to enter or leave, but does allow energy to enter or leave.
