Acopper rod that has a mass of 200.0 g has an initial temperature of 20.0°c and is heated to 40.0°c. if 1,540 j of heat are needed to heat the rod, what is the specific heat of copper?

Heat gained in a system can be calculated by multiplying the given mass to the specific heat capacity of the substance and the temperature difference. It is expressed as follows:

Heat = mC(T2-T1)

1540 = 200.0 (C)(40 - 20)

C = 0.385 J / g C

Hope this answers the question. Have a nice day.
