# Statistical Thermodynamics: Zeroth law of thermodynamics

Calculate the temperature increase when $400 \text{ J}$ of heat is applied to $46.8 \text{ g}$ of $\ce{NaCl}.$

 Details and assumptions:

• The molar heat capacity for $\ce{NaCl}$ is $C_p = 50 \text{ J} \cdot \text{mol}^{-1} \cdot \text{K}^{-1} .$
• The formula weight of $\ce{NaCl}$ is $58.5 \text{ g/mol}.$
