Closed System
Definition
A closed system refers to a physical system that does not exchange matter with its surroundings but can exchange energy with them. In other words, no mass enters or leaves the system, but energy can be transferred in or out.
Analogy
Think about a sealed water bottle filled with water. The water bottle represents a closed system because no water can enter or leave it, but heat can still be transferred between the water inside and its surroundings.
Related terms

Conservation Laws: As mentioned earlier, conservation laws apply to closed systems where certain physical quantities remain constant over time.
Energy Transfer Mechanisms: These mechanisms include processes such as conduction, convection, and radiation through which energy can be exchanged between a closed system and its surroundings.
