A question has been proposed in my CHM class. I believe I have the answer but just wnated to rund it by the experts for varification.
Question: As a purity check for industrial diamonds, a 10.25 carat diamond is heated to 74.21 degree C and immersed in 26.06 g of water in a constant-pressure calorimeter (1 carat = 0.2000 g). The initial temperature of the water is 27.20 degree C. Calculate delta T, of the water and the diamond ( C diamond = 0.519 J/g. K.)
My answer:
I assumed STP. In making this assumption, the delta T of water is 2.2 degress C.
The delta T of the diamond is 49.21 degrees C.
Does this seem to be resonable? For this problem, can it be just that simple???
Thanks in advance for any inputs!
