What are open, closed and isolated systems ? Give one example for each.

Explanation

Types of systems. The systems are classified into three types. These are :.
a) Open system : A system which can exchange matter as well as energy with the surroundings is called an open system.
Ex: Evaporation of water from a beaker presents as open system. Here vapours of water (matter) go into the atmosphere and Open system heat (energy) required is absorbed by water from the Surroundings,
b) Closed system: A system which may exchange energy but not matter with surroundings is called a closed system.
Ex: Consider boiling of water in a closed metallic vessel. Here, heat is transferred from the burner (surroundings) to the system. Steam remains inside the vessel. Thus, matter is not exchanged.
c) Isolated system: A system which can neither exchange matter nor, energy with the surroundings is called an isolated system.
Ex: Take some water in an insulated vessel and put a small piece of sodium metal in it. An exothermic reaction takes place. Neither hydrogen gas (matter) nor heat (energy) is transferred to the surroundings.
