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
by mixing together
The Earth exchanges mass and energy with the rest of the cosmos. This means that the Earth is an open system.
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.
Because in an open system matter is leaving and entering, which would change the mass, effecting your results.
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.
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.
an open system through which both energy and mass can transfer
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.
