==Key Stage 4==
===Meaning===
[[Closed System|closed system]]s are [[system]]s in which [[mass]] cannot get in or out, but energy can.

===About Systems===
: A [[system]] is an [[object]] or a group of [[object]]s being studied.
: In [[Closed System|closed system]]s [[energy]] can enter and escape. This may appear as an increase or a decrease in [[temperature]] caused by the surroundings but not by the [[system]].
: In a [[Closed System|closed system]] [[mass]] cannot enter and leave.
: In these [[Closed System|closed system]]s the law of [[Conservation of Mass]] can be [[observed]] but the law of [[Conservation of Energy]] cannot.
