The light bulb is a closed system: no mass transfer.
The radiator should be analyzed as an open system since mass is crossing the boundaries of the system.
closed
An open system is one where neither the total mass nor the total energy is conserved. In an open system, matter and energy can flow in and out of the system, leading to changes in both mass and energy within the system over time.
by mixing together
In an open system, neither total mass nor total energy is typically conserved. This is because open systems can exchange matter and energy with the surrounding environment, leading to changes in mass and energy within the system itself.
A system is considered a closed system when no mass crosses its boundaries, while a control volume is an open system where mass can enter or leave.
An open system is a system which can be affected by external factors. Energy of the system can be altered, total momentum, charge, etc. In a closed system, energy, mass, momentum, charge and other properties are conserved.
Open systems are computer systems that gives some combination of interoperability, portability, and open software standards. While in physics an open system is a system in which energy can be lost or gained from the environment.
car radiator is an open system...because hot water is coming in and rejecting heat..this means mass and energy r flowing in and out from the system..it is a control volume through which mass is flowing..
A system which can exchange mass as well as matter with the surroundings is called anopen system.Example:- Heating of CaCo3 in an open bulb.A system which can exchange energy but not matter is called a closed system.Example:- Calcination of CaCo3 in a sealed bulb.
In terms of chemistry, an open system is one which exchange both matter and energy with the surroundings. For example a test tube, beaker , flask , etc. All living systems are also open system.
