It depends on who you ask. Biologists will likely answer that the atmosphere is a closed system because it is mostly self-contained. Forces like solar winds, magnetic storms, and electromagnetic radiation, though, constantly bombard, penetrate, and interact with the atmosphere. So it is not, realistically, a closed system.
This is an open system. In an open system, energy can be exchanged with the surroundings, but not matter.
In an open system, momentum can be exchanged with the surroundings, while in a closed system, momentum remains constant within the system and cannot be exchanged with the surroundings.
In an open system,both energy and matter flow.In an closed system only energy flow.In an isolated system neither energy nor matter flow.
The system with friction is considered closed because it does not exchange energy or matter with its surroundings.
A closed system does not allow for energy or matter to enter or leave the system.
An open ventilation system simply lets the crankcase fumes vent into the atmosphere. A closed system reburns the crankcase fumes via the pcv valve.
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.
The light bulb is a closed system: no mass transfer.
