==Key Stage 4==
===Meaning===
[[Open System|open system]] are [[system]]s in which [[mass]] and [[energy]] can get in and out.
===About Systems===
: A [[system]] is an [[object]] or a group of [[object]]s being studied.
: In [[Open System|open 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 an [[Open System|open system]] [[mass]] can enter and leave. This may affect a [[Chemical Reaction|chemical reaction]]s taking place in that [[system]].
: In [[Open System|open system]]s the laws of [[Conservation of Energy]] and [[Conservation of Mass]] cannot be observed.
