Calculate the heat that must be supplied to a 500g copper kettle containig 750 g of water to raise its temperature from 23 degrees to the boiling point of water, 100 degrees.
q=MCT
qwater= 750 x 4.184 x 77= 241626 J
qcopper= 550 x .38 x 77= 16093 J
241626 + 16093 = 257719 J
The answer in the back of the book says 26000. So I'm not sure if its right and they rounded up or I did it wrong and just got lucky that my answer was close.
