Answer:

#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, and#Delta T# is the change in temperature.

#2.000*10^3J = 4g * 5°C*C_s#

#C_s = (100J)/(g*°C)#
