Definition of Specific Heat Capacity

Specific heat capacity, often referred to simply as specific heat, is a fundamental thermodynamic property that characterizes the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius (or Kelvin). Expressed in joules per kilogram per degree Celsius (J/kg°C) or in British thermal units per pound per degree Fahrenheit (Btu/lb°F), specific heat capacity is a crucial parameter for understanding the thermal behavior of materials.

At its core, specific heat capacity reflects a material’s ability to store and release thermal energy. It serves as a measure of the substance’s responsiveness to temperature changes, illustrating the amount of heat energy needed to alter its temperature. This property plays a pivotal role in determining the thermal performance of materials in various applications, including construction.

For building materials like brick, specific heat capacity influences the material’s capacity to retain and dissipate heat, thereby impacting the thermal stability and energy efficiency of structures.
