Specific heat capacity, often simply referred to as specific heat, is a physical property of a substance that measures the amount of heat energy required to raise the temperature of a unit mass of that substance by one degree Celsius (or one Kelvin). The specific heat capacity is typically denoted by the symbol \( c \) and is expressed in units such as joules per kilogram per degree Celsius (J/kg·°C) or joules per kilogram per Kelvin (J/kg·K).
