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:

$q = m {C}_{s} \Delta T$,

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)
