Ok so I have this paragraph or 2 to write for school tomorrow, and I've researched tons and I can't find a thing on it. Here's the question

We have to write about one substance that hardens when exposed to high temperatures, such as cement, clay (can't use that one, it was the example), cookie dough, mud, ect. We have to explain why it has these properties that allow it to harden, rather then soften and melt such as butter and chocolate.


Can someone PLEEEEASE help me?!

A metal object with a mass of 19g is heated to 96C (degrees centigrade), then transferred to a calorimeter containing 75g of water at 18C. The water and metal object reach a final temperature of 22C.

a)What is the specific heat of the metal in cal/gC and in J/gC?

b) What is the metal?

I have this question on my study guide and it's not a turn in question for chemistry. The formula for specific heat is

Specific Heat (SH=heat/mass x difference temperature)

Yes, I did see the Mythbusters episode. But what are your opinions on the so-called "Whirlpools of Death", because at the velocity of the world's largest known whirlpool, Adam (one of the hosts of Mythbusters) would have more than survived with that equipment in that scaled-down version, although he did emerge with nausea... namely vomiting. Sorry, I am rambling. Your opinions on "whirlpools of death"?
