Uranium hexafluoride is a chemical compound consisting of one atom of uranium combined with six atoms of fluorine. It is the chemical form of uranium that is used during the uranium enrichment process. Within a reasonable range of temperature and pressure, it can be a solid, liquid, or gas. Solid UF6 is a white, dense, crystalline material that resembles rock salt.....thats interesting
Gooood! And you must also mention that it is too corrosive.

Density is mas per unit of volume, and AFAIK there is a difference between mass and weight. Mass does not change, while weight does due to g.

Mass is in Kg etc... and as you said - is constant.

 

Weight is in Newtons (ans as you said can change with g) as it is the force which this mass exerts under gravity.

 

 

Thus - a 10 kg block on the moon is still a 10 kg block, but weighs alot less (about 1/6th?)

Maybe she's the author of that:rolleyes:

 

Well, there is a "non-zero probability" of that (;) ), but it's not very likely.
