Closed Systems

A closed system is a type of system in which the exchange of matter with the surroundings is not possible, but energy can be transferred in or out of the system.

Characteristics of Closed Systems

• Does not exchange matter with the surroundings
• Allows for the transfer of energy
• Can be a physical system, such as a sealed container, or a theoretical concept, such as the Earth's ecosystem

Examples of Closed Systems

Some examples of closed systems include:

1. A sealed terrarium
2. An insulated thermos
3. The Earth's biosphere (as a theoretical closed system)

Study Guide

When studying closed systems, it's important to understand the following concepts:

1. Exchange of Matter: Closed systems do not exchange matter with the surroundings. This means that the total mass of a closed system remains constant over time.
2. Transfer of Energy: While matter cannot enter or leave a closed system, energy can be transferred into or out of the system. Understanding the different forms of energy and how they interact with closed systems is important.
3. Applications: Be familiar with real-world examples of closed systems and understand how they function in various contexts, such as environmental science, engineering, and thermodynamics.

By mastering these concepts, you will have a solid understanding of closed systems and their role in the natural world and scientific principles.
