A copper 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? Use q equals m C subscript p Delta T..
0.0130 J/(gi°C)
0.0649 J/(gi°C)
0.193 J/(gi°C)
0.385 J/(gi°C)

D.  0.385 J/(gi°C)

Explanation:

Heat = mC(T2-T1)

1540 = 200.0 (C)(40 - 20)

C = 0.385 J / g C

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.
