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:
Study Guide
When studying closed systems, it's important to understand the following concepts:
- 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.
- 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.
- 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.

Earth/Space Science: Students will use scientific skills and processes to explain the chemical and physical interactions (i.e., natural forces and cycles, transfer of energy) of the environment, Earth, and the universe that occur over time.
Earth History: Explain how sedimentary rock is formed periodically, embedding plant and animal remains and leaving a record of the sequence in which the plants and animals appeared and disappeared.
Explain how sedimentary rock buried deep enough may be reformed by pressure and heat and these reformed rock layers may be forced up again to become land surface and even mountains.
