Entry from British & World English dictionary
The number of heat units needed to raise the temperature of a body by one degree.
- The time constant depends on both thermal conductivity and thermal capacity of the body itself, and the rate at which heat exchanges with the environment.
- The thermal capacity of materials changes slightly with temperature primarily due to changes in density, and very dramatically at phase transitions, such as ice melting and water boiling.
- The water has quite a high thermal capacity and because of the wind, any extra heat is distributed across the upper layer.
