lit buld has insignificantly more mass but significantly less weight

>>8211899
if by weight then is the heated one

>>8211899
>>8211926
the one turned off ways more.
the heat from the lamp makes the bulb less dense

>>8211899
if the inside is not a vacuum the heated bulb weighs less due to buoyancy

Either of you niggers want to explain your ideas?

Personally, I think the heated bulb should get slightly larger, but still have the same mass, so it's slightly more buoyant in air, but not actually lighter.

Also...

>lit buld has insignificantly more mass but significantly less weight
Are you implying gravity itself has changed?
Weight IS mass * gravity, or am I missing something?

>>8211938
a lit buld is hot, there is an electrical current passing through the wire both of which carries some energy, thermal or electric, and we all know that E = mc^2, so it adds a few attograms

but the buld also expands a little due to heat (whether it has an inert gas inside or near-vacuum) taking up more volume and experiecing a greater buoyant force in the surrounding air, this adds up to a few nano- or microgramms and could actually be measured

Attograms seems likely to be smaller than some other incidental effects like outgassing, or something else I can't be bothered to think of,

>greater buoyant force in the surrounding air
Being more buoyant doesn't actually make something weigh less.

>lighter because the heat makes it more buoyant

You can't make a solid object more buoyant without changing its shape or without removing and replacing mass with less mass.

>>8211899
they both weight the same
also who the fuck is gonna care how much a lit bulb weighs anyway?

>believing solids don't expand at all when heated

>>8214102
Ice doesn't.

>>8214392
Nice one! You got me! I should have been more concise and said:
>believing no solids expand when heated
