Does Heat Impact Analytical Balance Readings?

Hot Items Should be Maintained at a Constant Temperature When Weighing on An Analytical Balance

Hot Items Should be Maintained at a Constant Temperature When Weighing on An Analytical Balance

Here is an interesting question posed by a Grade 9-12 student.  Essentially she is inquiring about the impact that a hot crucible will have on the mass when weighed on an analytical balance.  The answers through the Ask a Scientist service are all over the place.  Some give a definite yes that the hot crucible will have an adverse impact on the readings due to the air currents generated by the heat.  Others are not so sure.  The sanest advice to the budding scientist was to try it out for herself and to observe the results.
