Chemistry question

[ibruegge]

Hello, made a promise of looking after my little brother in law during homework. Now I'm stuffed as I can't come up with the answers / examples.

 

remember changes of matter phases. Solid, liquid and gas. So an example is Ice, water and water vapour; we are looking for another example where the liquid phase are know as a useful product. We tried everything from gold, iron etc. Boiling point, melting point in periodic table does not help if we can't label the liquid phase:(

That is what we are struggling with tonight. Because it must bé an example used in all three phases.

 

 

Any ideas?! Thanks

Mercury? It's been so long...

[JCA12]

Liquid nitrogen maybe. But not sure about solid phase. What about mercury?

[pastapouch]

won't know the english swael, stikstof, chlorine?

maybe this can help

must it be any material where all three phases are usefull ?

 

or just items from the periodic table ?

 

CO2 might be one. As a liquid for storage, as a gas for fire extinghuishers (sp) and as a solid for keeping things cold.

 

WHat about fisher tropsch chemicals ?

 

Oh yes, hydrocarbon fuels ? petrol...... gas and liguid umm solid may be an issue

The only liquid elements are mercury (Hg) and bromine (Br).

But in order to make other liquids and gases some elements need to be combined. Or chemically changed to create a gas.

ie water is H20 hydrogen and oxygen 2 gases combined to make a liquid

Elements can be combined to make solids also.

Naturally occurring solids are copper, zinc, etc. They are fairly easy to spot on the periodic table.

I guess any material useful in three states would be a winner. Thanks everyone, I start feeling proper stupid (or old) :-)

Best I can do is liquid LPG in gas cylinders; liquid oxygen and hydrogen to power rockets (the moon kind, not Guy Fawkes!). But solid?

 

Glue: gas to sniff, liquid to pour and solid as glue. Hmmm, may not go down that well. Go sit in the corner.

Buthane - gas LPG, liquid for transport and for rockets its a solid... I think

nice one !!

[pastapouch]

nice one !!

If its an element...I can't rememebr, was in Matric in Oh my goodness' 93...and my final mark for Science was 27%Hg LOL

Awesome! Thanks

I can't think of an example, but when in doubt confuse the teacher by saying "the phases of matter include the usual 3 but also plasma, beams and Bose-Einstein condensates"... that should get him extra points (or a good hard klap!)
