Homework Help: Thermodynamics

Posted by Danny on Friday, July 5, 2013 at 1:55am.

27.300kg of Copper at 35.000 degrees Celsius receives 460.000kJ of heat. Calculate the final temperature of the metal.
ANS = degrees Celsius
Copper specific heat = 0.39kJ/kg degrees Celsius.
Q = mc (t2 - t1)

Q = 460.000kJ
m = 27.300kg
c = 0.39kJ/kg
t1 = 35 degrees Celsius
t2 = Final temperature

To find the final temperature how would you change the formula?
t2 = Q/ mc + t1 ?

Please let me know, I'm a little confused. Thank you.
