The constant 321 K is called the Debye temperature of NaCl, D , D , and the formula works well when T < 0.04 D . The reduced heat capacity must be compensated by circulating more fluid. K. Specific heat capacity may be reported in the units of calories per gram degree Celsius, too. The SI unit of heat capacity is joule per kelvin (J/K).. Heat capacity is an extensive property.The corresponding intensive property is the specific heat capacity, found by dividing the heat capacity of an object Notes of Parameter of A325 Bolts in ASME B18.2.6 -2019 . If it's temperature increased by 4.09 K, what is its specific heat in J / kg K? K) at 25 C) the second-highest among all the heteroatomic species (after ammonia), as well as a high heat of vaporization (40.65 kJ/mol or 2257 kJ/kg at the normal boiling point), both of which are a result of the extensive hydrogen bonding between its molecules. Source: Specific heat values are obtained primarily from the property routines prepared by The National Institute of Standards and Technology (NIST), Gaithersburg, MD.

Specific heat of aluminum is 0.91 kJ/kg 0 C and the heat required can be calculated as. The properties c v and c p are referred to as specific heats(or heat capacities) because under certain special conditions, they relate the temperature change of a system to the amount of energy added by heat transfer. Hence, its derived \(SI \)unit is \(J kg1 K1\). Specific Heat Problems. The relationship between heat and temperature change is usually expressed in the form shown below where c is the specific heat . The specific heat capacity of solid aluminum (0.904 J/g/C) is different than the specific heat capacity of solid iron (0.449 J/g/C). m; 1 g/cm3 = 1 kg/dm3 = 1000 kg/m3; 1 GPa = 1 kN/mm2; 1 MPa = 1 N/mm2 K (T 321 K) 3.
