Question

Open system and Isolated system :

✓

Answer

Open system:

An open system can exchange matter with the surroundings.
It can exchange energy with the surroundings.
In this, the total amount of energy does not remain constant.
Example : Hot water kept in an open beaker.

Isolated system

An isolated system cannot exchange matter with the surroundings.
It cannot exchange energy with the surroundings.
In this, the total amount of energy remains constant.
Example : Hot water kept in a thermos flask.
