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

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.

the answer is 1 i believe
