Answer:

The answer is 10.507 KJ

Step-by-step explanation:

The formula you need to use for this question is MC(delta)T:

M=Mass ( 175g)

C=Specific Heat ( depends on the element, copper=0.38 j/g.k )

and T= Temperature, where you find the change in temperature by minusing the final T with the initial T.

so, (175g)(0.38)(184-26)= 10,507 J

since we need the answer in KJ divide 10,507 by 1000

10,507/1000 = 10.507 KJ
