What is the Difference Between Isolated System and Closed System?

🆚 Go to Comparative Table 🆚

The main difference between an isolated system and a closed system lies in the exchange of matter and energy between the system and its surroundings:

  • Closed System: In a closed system, matter within the system remains constant, but energy is allowed to be transferred from the system to the surroundings and vice versa. A closed system does not allow matter to enter or leave, but does allow energy to enter or leave. Examples of closed systems include a covered pot on the stove and a tightly fitting lid on a pot.
  • Isolated System: An isolated system is one where neither matter nor energy can be exchanged between the system and its surroundings. An isolated system is a theoretical concept, and there are no truly isolated systems in reality. A perfect isolated system is hard to come by, but an insulated drink cooler with a lid is conceptually similar to a true isolated system.

In summary, while both closed and isolated systems do not allow the exchange of matter, closed systems allow the exchange of energy, whereas isolated systems do not allow the exchange of either matter or energy.

    • Comparative Table: Isolated System vs Closed System

    Here is a table comparing the differences between an isolated system and a closed system:

    Feature Isolated System Closed System
    Matter Exchange Does not allow exchange of matter with surroundings Does not allow exchange of matter with surroundings
    Energy Exchange Does not allow exchange of energy with surroundings Allows exchange of energy with surroundings
    Examples Thermos, insulated drink cooler Covered pot on the stove, pressure cooker

    An isolated system does not allow either matter or energy to enter or leave, while a closed system does not allow matter to enter or leave but does allow energy to enter or leave.
