What will be the final temperature if 2000g of copper at 95 degrees loses 10 kcal of heat?

    -10,000 = 2000 x specific heat Cu x (Tfinal-95)
    Sole for Tfinal.

    81.9 degrees

    I skipped through it but didn't get that number. My best guess is that you looked up the specific heat of copper and found 0.385 but that number is joules/g. You must convert that to calories OR you must convert the 10,000 calories to joules.
    Convert 0.385 J/g to calories by dividing by 4.184. Something like 40 C or so should be the answer.
