A closed system allows for the exchange of energy but not matter with its surroundings. For example, a thermos can keep a beverage warm by transferring heat but does not allow the drink itself to escape.
A description with illustration of Open, Closed and Isolated Systems in thermodynamics - chemistry.
Closed Systems: In contrast to open systems, closed systems allow the transfer of energy but restrict the exchange of matter. An excellent real-life example is a sealed pressure cooker.
In the study of thermodynamics and chemistry, the concept of closed systems emerges as a fundamental pillar for the detailed understanding of energy processes and chemical reactions.
Some examples of thermodynamic systems are washing machines, refrigerators and air-conditioners. Air-conditioner is a closed system that circulates refrigerant inside the system, altering the pressure
Closed systems are sometimes described as systems that only allow energy to enter and leave, but not matter. In this case, a closed water bottle is a closed system.
At the same time, thermodynamic systems were mainly classified as isolated, closed and open, with corresponding properties in various thermodynamic states, for example, in states close to
If the matter that it transforms into energy is neglected, the sun is an example of a closed system, which does not exchange matter with its environment, but does exchange energy (solar radiation, sunlight,
Watches and clocks tend to form a prominent example of closed systems as they allow the conversion of energy from one form to another, but prohibit the exchange of matter between the system and

The classification of thermodynamic systems arose with the development of thermodynamics as a science. Theoretical studies of thermodynamic processes in the period from the first theory of heat engines (Saadi Carnot, France, 1824) to the theory of dissipative structures (Ilya Prigozhin, Belgium, 1971) mainly concerned the patterns of interaction of thermodynamic systems with the environment.
At its core, a closed system is meticulously designed to allow energy transfer across its boundary but strictly prevent any mass transfer. Imagine a perfectly sealed container: heat or light can pass
