Your body is an example of an open system. This is because open systems exchange both matter and energy with an outside system.
2. CLOSED SYSTEMS
An example of a closed system is the earth, because it obtains lots of energy from the Sun but the exchange of matter with the outside is almost zero. In a closed system, energy but not matter is exchanged with an outside system
3. ISOLATED SYSTEMS
An example is a closed thermos bottle. This system do not communicate with the outside in any way. Isolated systems can exchange neither energy nor matter with an outside system.
