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 these factors can affect the mass balance of the system, making it difficult to accurately study the conservation of mass. In an open system, it is difficult to keep track of all the inputs and outputs, and any errors or inaccuracies can greatly affect the results. A closed system, on the other hand, allows for better control and monitoring of the mass balance, making it more suitable for studying conservation of mass.
