Science Buddies: "Ask an Expert"

Hello,

Yesterday I mixed urea and water together and it turned cold.
I would like to know why it turned cold.

thaks for your help!


p.s. I searched all over google.

Hi coinjunk2,

Some websites to try are:

http://www.arff.info/forums/archive/index.php/t-590
http://www.osti.gov/energycitations/pro ... =2&start=0
http://www.addl.purdue.edu/newsletters/ ... _smp.shtml
http://www.cvm.uiuc.edu/vdl/AppenF_man.html

Note: there are lots of areas to explore on each of these pages and ideas for science projects!

I did not vet the pages to see if they are appropriate for someone at the junior high school/high level, so you may need help going through some of the pages.

Please don’t hesitate to ask.

Thanks and thanks for the interesting project!

By the way, I’m using a different web search engine, copernic, at http://www.copernic.com. I actually purchased Copernic Agent Professional, and it has been money well spent.

Hi coinjunky2,

Please excuse the typo in your screen name. Oops. Mea culpa (My fault). I’m sorry.

Some notes:

1. My typo in your screen name is shameful behavior, and all more reason to use cut and paste, which is more reliable, on important items. (Even when the alternative of just typing looks faster.)
2. Always run spell check. Particularly after the last typing.
3. Proofread, proofread, proofread. Again. particularly after the last typing.
4. Note this is all relevant material. To be effective in any field (in our case science), one has to be effective on the web.
5. I know after this posting, I’m personally going to under a magnifying glass. Please be gentle. After all, I am a sciencebuddies Volunteer, with a ”V”.

Thanks.
