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. Back to top   Ads Advertising Sponsor Bill Penrose Guest Posted: Mon Jun 30, 2008 12:47 am    Post subject: Re: Is there a material that gets heavier when heated?

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. -- Dirk http://www.transcendence.me.uk/ - Transcendence UK Remote Viewing classes in London Back to top   Ads Advertising Sponsor N:dlzc D:aol T:com (dlzc) Guest Posted: Mon Jun 30, 2008 5:37 am    Post subject: Re: Is there a material that gets heavier when heated?

I am a non-chemistry person, as you can tell. 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? http://www.howstuffworks.com/question663.htm It is really uncommon to find a material that gets more dense when heated.

Is there such a thing. I am a non-chemistry person, as you can tell. 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!!!
