I am looking for a material that will get heavier when heated BUT cool
back down to regular weight when not exposed to the heat. Is there
such a thing. I am a non-chemistry person, as you can tell.
Thanks in advance. |

You're breaking a major natural law here. Watch out for the Physics
Police.
What do you want to accomplish?

No
Actually, it depends what you mean.
Silver, for example, absorbs oxygen from the air when heated to its
molten state. Therefore it gets heavier (because there's more 'stuff' in
the crucible). It outgasses as it cools.

All materials when heated get heavier, because energy (even heat
energy) represents mass. But measuring such a miniscule change
will be nigh impossible.
What you may be interested in is a material that gets more dense
when heated, such that it might float or sink at a given
temperature?

It is really uncommon to find a material that gets more dense
when heated.

My company specializes in materials which
exhibit non-Newtonian mass characteristics
and non-Newtonian linear momentum. Could
you specify exactly how much mass increase
your application requires? Then, we can
quote you a price.
Is it okay if the material is a liquid?
Our liquid products division has a
water-soluble additive which greatly
increases the compressibility of liquid
water.
Hope to hear from you soon! Go to us,
Acme Unobtainium Corporation to satisfy
your most demanding requirements!
We are the industry leader!!! |
