Check out Mythbusters...i think they did a show on this.\nhttp://dsc.discovery.com/fansites/mythbusters/mythbusters.html

Sorry, but with the time you spent typing these questions you could of looked them up in your physics book or googled them.  Sometimes getting others to do your leg work isn't always the best answer to a problem.  Good Luck in your new class!

Lol\nI actually did a test like this for my nephews science project last year.  Unless the formulas have changed the differences are completly negligent.  Their lasting time is about the same.

This may not be the simplist answer, but you may be able to read it and make it simple for him.\n\nGood luck.\n\nHeres the link:\n\nhttp://www.newton.dep.anl.gov/askasci/chem00/chem00802.htm

OMG!\ni have the same question!\nmine is:\nA piece of an unknown metal has a mass of 20.0 g and at 100.0 C is placed in a styrofoam cup calorimeter containing 50.7 g of water at 22 C. If the final temp is 27.2 C, calculate the specific heat capacity of the metal. Assume that all the energy lost by the metal is gained by the water.\n\nok, haha fine, not the SAME question, but close enough. But, i'm uber confused. ><

The 'science guru' is right, but I'll chime in to try and help you wrap your mind around it. \nThe slower magma cools the bigger the crystals in it get. The deeper the magma is in the earth the more it is insulated (like a pizza in one of those pizza delivery bags) and so it cools lots slower the deeper it is.\nThe faster the magma cools the smaller the crystals in it. Since the earth insulates the magma it has to get closer to the surface before it can cool fast enough to have small crystals.\nIf you have two different sizes of crystals then you must have two different rates of cooling.\nThe crystals that can form at higher temps start forming first, of course, and then, when the magma gets pushed up nearer the surface the rest of the material cools quickly into small crystals that surround the larger ones.\nDoes that help?

What class was this in? What grade level? What text were you using?  I may be able to help you if I know the context in which the question was raised. I have a feeling that I am not getting all the information you had. Please tell me and maybe I can help. I am an old chemist and microbiologist.

Whoa, now that is a huge topic that would be impossible to explain in a simple answer. But I got an an idea... open your text book and read the answer, it will certainly explain it better than what can be said here.

I am not really sure why but the guys on Myth Busters did this experiment on their show on the Discovery Channel. There is a little blurb here: http://dsc.discovery.com/fansites/mythbusters/episode/episode_02.html\nand more info on the experiment here:\nhttp://www.eepybird.com/science1.html\nhope that helps with your science fair project! good luck!
