Quizplus · Accepted Answer

A closed system is one in which no matter enters or leaves, but energy can move freely in and out. Both options A (open) and C (equilibrated) state that energy moves freely in and out, but option A allows for the possibility of matter entering or leaving the system. Option B (feedback) refers to a process of adjusting a system based on its output, and is not directly related to the movement of matter or energy.
