**Amber**, Wednesday, April 6, 2011 at 2:25pmThe trick is that the heat lost from the metal is equal to the heat gained by the water.

So q lost = f gained. Since the metal went from 100.0C to 32.5C I'd say it lost. The water went from 20.0C to 32.5C, so it gained. "q" then represents the metal and "f" represents the water.

Now apply the following formula to solve for "q" and for "f":

(mass)(temp change)(specific heat).

What it should look like is this, (mass)(temp change)(specific heat) = (mass)(temp change)(specific heat).

Now plug in the values.

Your metal has a mass of 14.00g. The water's mass is 11,000g (which is 11mL).

Temp change of the metal was 100.0C down to 32.5C, so 67.5C. Temp change for the water was 20.0C up to 32.5C, so 12.5C.

Specific heat of your metal is "x" which we're solving for. Specific heat of water is 1.00cal/g x C.

I can't write out the equation on this web page. Fill in all the parenthesis making one set equal to the other. And then solve for x.
