Answer 2

Closed System In Thermodynamics

A closed system is a system that exchanges only energy with its surroundings, not matter.

In thermodynamics, a closed system can exchange energy (as heat or work) but not matter, with its surroundings. An isolated system cannot exchange any heat, work, or matter with the surroundings, while an open system can exchange energy and matter.

For a simple system, with only one type of particle (atom or molecule), a closed system amounts to a constant number of particles. However, for systems which are undergoing a chemical reaction, there may be all sorts of molecules being generated and destroyed by the reaction process.

Mathematically,

$\boxed{\bold{{\displaystyle \sum _{j=1}^{m}a_{ij}N_{j}=b_{i}}}}$

Examples

• Boiling the water in a pan without cover.
• Aircraft refrigeration system.
