Key Stage 4

Meaning

Closed systems are systems in which mass cannot get in or out, but energy can.

About Systems

A system is an object or a group of objects being studied.

In closed systems 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 mass cannot enter or leave.

In these closed systems the law of Conservation of Mass can be observed but the law of Conservation of Energy cannot.

A closed system can be made by sealing a container with a lid. For example a test tube with a bung or a Conical Flask with a balloon to collect gases that would otherwise escape.
