C_s = (100J)/(g*°C)

In English: it requires 100J of energy to raise one gram of this substance one degree celsius/kelvin.

Explanation:

We're looking for the equation that relates all of these variables:

q = mC_sDeltaT,

where q is the energy in Joules (J), m is the mass, C_s is the specific heat, andDelta T is the change in temperature.

2.000*10^3J = 4g * 5°C*C_s

C_s = (100J)/(g*°C)
