Why are open systems inappropriate for studying the conservation of mass?
Heat can escape from or enter the system.
Matter may be created or destroyed within the system.
Matter may be lost to or gained from the surroundings.
The sample may become contaminated.
All of the above reasons make open systems inappropriate for studying the conservation of mass because they violate the fundamental principle of the conservation of mass, which states that the total mass of a closed system remains constant over time, as no mass is lost or gained. In an open system, there is a flow of matter and energy between the system and its surroundings, making it difficult to accurately measure the mass of the system and trace its changes over time.
