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.

Q= 460000 J
m = 27.300kg
c = 390 J/kg
t₁ = 35℃
t₂ = Final temperature in ℃
t₂ = Q/mc +t₁ = 460000/27.3•390 + 35 =43.2 +35 = 78.2℃
