I am verifying the answers generated by an automatic system to the following question: What implication(s) does the law of conservation of matter have for humans? Suggested answer: By contrast, for a thermodynamically closed system (i.e., one which is closed to exchanges of matter, but open to exchanges of non-material energy, such as heat and work, with the surroundings) mass is (usually) only approximately conserved. Should I validate this answer?
