Answer: A closed system is a physical system in which energy like heat or work can be exchanged but not matter with the surrounding.
A closed system is often confused with an isolated system. An isolated system can transfer energy but cannot exchange work, heat, or matter with the environment. On the other hand, a closed system can transfer energy as well as can exchange work, heat, or matter with the environment.
Laws of Thermodynamics in a Closed System
Following are the laws of thermodynamics in a closed system:
According to the first law of thermodynamics, the change in internal energy is equal to the added work and heat.
The second law of thermodynamics implies the closed system's entropy increases with the heat absorbed and the work dissipated.
The conservation of masses can also be applied in this system in which mass remains constant.
A Closed System is one in which
A system that can exchange heat and work but not matter with the surroundings is known as a closed system.
