Q1.4 The U.S. National Institute of Standards and Technology (NIST) maintains several accurate copies of the international standard kilogram. Even after careful cleaning, these national standard kilograms are gaining mass at an average rate of about lug/y (y = year) when compared every 10 years or so to the standard international kilogram. Does this apparent increase have any importance? Explain.
