Specific Heat Capacity

Amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius (or one kelvin); commonly denoted c (units J·kg^-1·K^-1).

The amount of heat required to raise the temperature of a unit mass of a substance by one degree (K) under specified conditions; often denoted c or cp when measured at constant pressure, with SI units J·kg−1·K−1; value depends on temperature, phase and thermodynamic constraints (e.g., constant‑pressure vs constant‑volume).

The amount of heat energy required to raise the temperature of a unit mass of a substance by one degree Kelvin (or Celsius); an intensive material property commonly denoted cp (at constant pressure) or cv (at constant volume) with units J·kg−1·K−1.
