Assuming that the pressure and temperature are standard, the specific heat of NaOH is 28.230 J mol-1 K-1 at 25 degrees Celsius. Specific heat capacity describes the physical measurement of the heat necessary per unit mass to increase the temperature one degree Celsius.
All pure substances that take part in chemical reactions have a unique heat capacity. Scientists take one gram of a substance to measure the heat capacity. Scientists use a specific equation for the specific heat of a substance, the mass of the substance, the temperature change and how much energy goes into the system and this equation is q=mCpDT.
