Question

A 300g piece of copper is heated and fashioned into a bracelet. The amount of energy transferred by heat to the copper is 6,500 J. If the specific heat of copper is 0.390 J/g0C, what is the change of the copper's temperature?

Answer 1

q = mC∆T

q = heat = 6500 J

m = mass = 300 g

C = specific heat = 0.390 J/g/degree

∆T = change in temperature = ?

6500 J = (300 g)(0.390 J/g/deg)(∆T)

∆T = 600/(300)(0.390)

∆T = 55.6 degrees
