Explanation:
Detailed explanation-1: -A closed system is a physical system that does not allow the transfer of matter in or out of the system. Hence, for a closed system mass does not change.
Detailed explanation-2: -We can also distinguish between open and closed systems: in an open system both matter and energy can enter or leave (we can keep track of both) whereas in a closed system the amount of matter is constant and only energy can enter or leave.
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.
