For my research I want a liquid which will not alter its properties below 500 degrees centigarde?

Question

I have problem. For one of my projects I want a liquid which will not change any of its properties, if it is heated to 400 degrees Centigrade.
Can any one tell me? I shall be extreemly thankfull to him.

Answer 1

This liquid you are talking about must have either metallic bonding or strong crystalline bonding. There is no hydrogen bond strong enough to hold a liquid in liquid form at 500 degrees centigrade. A metallic bonded metal that would remain liquid between room temperature and 500 degrees is mercury. As for crystalline bonding, you'll have to find that out yourself because none comes to mind at the moment.

Answer 2

Your initial statement is unsolvable because all liquids (except maybe liquid Helium) will solidify when cooled sufficiently.
There will always be thermal volume change(a property) when heated.
Most liquids will solidify (change state; a property) at different pressures.
Your question is not well formed. More parameters are needed to give a meaningfull answer.
Would a particulate fluid work for your problem?
(sand or millions of microscopic ball bearings.)

Answer 3

Liquid sodium is an answer but will be solid at room temperature and is difficult to handle. Mercury boils off but there are some other metals and other materials also. Depending on the experiment, you need to look at the options. Laboratory catalogs should give you some ideas. If you can write separately to me, we can discuss.

Answer 4

mercury....i think inert gas compounds can also be usefull

Answer 5

liquified argon......neon....krypton

What is the research..? i may help u better then...

Answer 6

wild guess... mercury?
