Closed Systems

A closed system is a type of system in which no matter is allowed to enter or leave the system, but energy can be transferred in and out of the system. This means that the total mass of the system remains constant over time, but the energy within the system can change. Closed systems are commonly studied in the fields of physics, chemistry, and environmental science.

Characteristics of Closed Systems:

• No exchange of matter with the surroundings
• Energy can be transferred in and out of the system
• Total mass remains constant
• Commonly studied in thermodynamics and environmental science

Examples of Closed Systems:

Some common examples of closed systems include:

1. A sealed terrarium
2. A closed container of gas
3. A thermos with a lid

Study Guide:

Here are some key points to remember when studying closed systems:

1. Understand the concept of matter and energy transfer
2. Be able to identify examples of closed systems in everyday life
3. Learn about the laws of thermodynamics as they apply to closed systems
4. Understand the implications of closed systems in environmental science and resource management

Remember to review the characteristics and examples of closed systems, and be able to apply your knowledge to real-world scenarios.

Good luck with your studies!
