WebJan 28, 2024 · The weighing errors caused by the buoyancy of air are often neglected when small, dense samples are weighed. Analytical balances are in most cases calibrated using steel-alloy weights, which have a precise density of 8000 kg.m −3 (Reichmuth et al. 2004). In the case of weighing samples of the same density as the calibration weight, … WebDec 26, 2024 · Buoyancy, otherwise called the upthrust, is the force acting in a direction opposite to the gravitational force that prevents a floating object from sinking.
