I've been working on it for two hours and I can't figure it out! It's probably very easy and I'm overworking it, but I can't do it!!!!

i found info from these sites. melting point, freezing point, boiling point.
http://chemistry.about.com/library/blar.htm
>>Argon has a freezing point of -189.2°C, boiling point of -185.7°C
http://education.jlab.org/itselemental/ele018.html
>>Melting Point: 83.80 K (-189.35°C or -308.83°F)


Boiling Point: 87.30 K (-185.85°C or -302.53°F)

the atoms that constitute your body are mostly empty space, and structures such as the chair you're sitting on are composed of atoms that are mostly empty space.

How can we, by analyzing the genetic material from only a FEW human beings, claim that we will understand all there is to understand about ALL human beings? If the idae is to understand DIFFERENCES among us, don't we need to examine the genetic code from MANY?

After watching "NOVA" last night on PBS about global warming and the incredible increase in glaciar movement due to melt water deep below the glacier ( between the glacier and solid rock ), will this glacier completely slide into the ocean in one event and cause a tsunami of hundres of feet high and posibly circle the globe?

Are government leaders in the U.S. aware of this posibility and thair's a conspiracy to hide the truth from the public?

Is it too late to do anything about it?

Is the U.S.A. to blame for what will happen to our planet?

Is this event the next "MASS EXTINCTION"?

So many question, so little answers...

What mass of steam initially at 150 degrees C is needed to warm 180 g of water in a 100 g glass container from 20.0 degrees C to 53.0 degrees C?

I have found the specific heats of the materials. I thought I should use Q=(m)(c)(delta T), but I can't figure out how to do that without the initial mass of the steam. Please help!

I am in the process of doing a project for a science fair exhabition and I'm interested in finding out as part of my project how I might be able the make a simple bar-magnet levitate through a series of magnetically charged coils (electromagnetic of course). Basically I'm trying to find out info about the circutes I might need and also the find out about the meterials I might need. I would be grateful if you could give me any info at all, even if you have info about URL's I might be able to go to on this subject. Thank for your help.

Write down the equation of all the points for which the sum of their distance from(0,a) and of their distance from (0,b) is equal to 6. Then describe the graph of this equation when a=b.

Now, I just don't know where to start on this. Guidance to solution is much appreciated!
