How is the law of conservation of mass affected by a system that is open to the surroundings?
An open system is described as a system that allows both mass and energy to escape. Therefore, you cannot prove the law of conservation of mass using an open system. For example, a beaker is an open system. Let’s say you boil your reagents. Some of it evaporates and leaves though the top of the beaker. This means that some mass will be “lost.” good luck!
