“The majority of people don’t realize that air from drafts or updrafts has mass,” Stafford states. read more “Mainly because we are now living in it and can’t see it, we have a tendency to disregard it.” He implies making it possible for sample, tare vessel, and equilibrium to reach mutual temperature equilibrium Anytime temperature variances are suspected.
