WebThe specific heat capacity of refractories is very important when they are used in heat exchange applications such as in blast furnace stoves or glass tank regenerators. However, the overall range of mean specific heat capacity of all refractories is not large, being approximately 0.7–1.2kJ kg –1 K –1 (see Table 4). WebIn the SI system, the specific heat is numerically equal to the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00°C. The SI unit for specific heat is J/(kg × K) or J/(kg × °C). (Recall that the temperature change ΔT is the same in units of kelvin and degrees Celsius.)
