Here is the problem, " a calorimeter is filled with 150.0 g of water at 24.10 degrees C. A 50.0 g sample of metal at 100.0 degrees C is dropped into this calorimeter and causes the temperature to increase a total of 5.40 degrees C. What is the specific heat of the metal?

I understand how to calculate J/g C, (q=mc* change in temp [C]), how do I find specific heat (c) when I don't know the heat absorbed by the calorimeter?

Many ores are obtained from large open-pit mines.
What would happen to this mine if the demand for
its ore decreased?
What would happen if the
demand increased?

Sorry for the brief dramatic opening, but between the Permian period at the end of the Paleozoic age and the beginning of the Triassic period of the start of the Mesozoic era there seems to be a mass extinction of living things. Obviously, it was not a complete extinction, but this article by Shu Zhong Shen, et al. in Palaeoworld shows a cooling, then a warming and references others that show it was global in nature. Could it be that what we are surmising as Global Warming today is just another of several natural events that periodically happen? There were no humans 248 million years ago, or were there?
