A 150.0g sample of a metal at 75.0C is added to 150.0g of water at 15.0C. The temperature of the water rises to 18.3C. Calculate the specific heat capacity of the metal, assuming that all the heat lost by the metal is gained by the water.

Ooh, a double post! As can be seen in the Math and Physics forum...

I wonder if you realize that the purpose of these forums is not to be an "answer service," but rather a place for discussion, debate and learning. Getting someone else to do your homework isn''t learning.

And if you can''t figure that Qmetal = Qwater, then you truly are dumb.

Don''t worry about me; I''m the blunt one.

Dude, of course Heat(water) = Heat(metal)

specific heat of water = 4.18 J/Cg
delta T for water = 3.3 degrees so

Heat(water) = (4.18)(150)(3.3) = 2069 J

But I don''t know the temperature change of the metal.

Of course, after a certain amount of time. The problem should''ve state the time or makes it clear.

Time is irrelevant to the solution of this problem. Go read your textbook.
