# Physics/Chemistry problem

## Recommended Posts

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.

Heh, I haven''t seen such a blatant "do my homework for me" post in awhile.

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.

um, the metal temperature should equilibrate with the water, no?

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.

And this relates to game development in what way...

I''m closing this, it''s the wrong forum for this type of question (..not to mention the wrong board )
