No. Heating and cooling do not change the mass of an object. Changes in temperature very often change the volume of an object, however, which means that the density of the object changes. Heating usually causes an object to expand, which means that its density goes down. Its mass, and therefore its weight, does not change.

∙ 13y agoGlass will expand when heated, with the exception of glass carefully chosen not to do so. Borosilicate glass has a very low coefficient of thermal expansion. And rather special glass is used to make astronomical telescope, where expansion of the glass will cause problems.
So the answer is 'it all depends'.

Does glass expand?
Glass expands and contracts according to the ambient temperature.
How do you make metal contract?
They expand ------- No, normally metals expand when heated.
Do all liquids expand when heated?
Liquids expand more than solids on heating
Why a glass jar can be easily opened if the metal lid is heated?
because metal will expand when it has been heated up
Why does water in a glass tube contracts first then expand when heated?
glass is a bad counductor of heat, so at first the glass flasks expands and its volume inside increases. the liquid which has not started to expand yet, drops to fill the extra volume inside
Why does a glass tumbler crack when you suddenly pour hot tea into it?
When we pour very hot water into an empty glass, the inner surface of the glass will expand as matter expands when heated. But the inner surface of the glass will expand more than the outer surface of the glass because more heat is applied to the inner surface of the glass.
Oil expand or contract when heated?
Oil does expand when heated and contracts when cooled.
Does glass looked different when heated opposed to glass not heated?
Yes, because if glass is heated it breaks, if glass is not heated it doesn't break.
Is liquid expand when heated?
Yes, in general a liquid will expand when heated. They contract when they are cooled.
Why do solids expand when heated even though their mass does not change?
BECAUSE the moncules are heated they expand because there gay and expand
Does matter expand or contract when it is heated?
Expand
Why a glass jar can open easily if the metal lid is heated gently first?
Heat causes the metal to expand, thus breaking the seal.
