Closed Systems in Science

A closed system in science refers to a physical system that does not allow the transfer of matter in or out of the system, but allows the transfer of energy. This means that the total amount of matter within the system remains constant over time.

Characteristics of Closed Systems:

• Do not allow the transfer of matter in or out
• Allow the transfer of energy (e.g., heat or light)
• Total amount of matter within the system remains constant

Examples of Closed Systems:

Some common examples of closed systems include a sealed terrarium, a closed bottle of soda, and a sealed thermos. In each of these examples, while energy can enter or leave the system, the matter remains constant within the system.

Study Guide:

Here are some key points to remember about closed systems:

1. A closed system does not allow the transfer of matter in or out.
2. Energy can be transferred into or out of a closed system.
3. The total amount of matter within a closed system remains constant over time.
4. Examples of closed systems include sealed terrariums, closed bottles of soda, and sealed thermoses.
