Uhmm.. i faced some problem with my experiment of finding the thermal conductivity of glass..i hope that someone can help me.(adsbygoogle = window.adsbygoogle || []).push({});

May i know the extimation of the thermal conductivity of a boiling tube??

isit the same as the thermal conductivity of pyrex glass??

when i want to find the radius of the boiling tube, should i take the reading of the external diameter divided by 2 or the internal diameter divided by 2??

and about the thickness of the boiling tube, its the external diameter deduct the internal diameter then divided by 2 isit??

i will really appreciate your help..
