Input (English): At low temperatures, Debye's model accounts for phonon contribution to this quantity. This quantity at constant pressure minus it at constant volume is the number of moles of gas times the gas constant. The Dulong-Petit law states that this quantity for metals is three times the(*) gas constant over molar mass. This quantity can be written as heat divided by mass times temperature change, and for water, its value is one calorie, or 4.184 Joules per gram degree Celsius. For 10 points, name this property, the amount of energy needed to raise the temperature of one gram by one degree.
Output (English): Science
