Also, explore many other unit converters or learn more about specific heat capacity unit conversions. The SI unit of heat capacity is joule per Kelvin (J/K). This is the SI unit of specific heat. The measurement of heat transfer using this approach requires the definition of a system (the substance or substances undergoing the chemical or physical change) and its surroundings (the other components of the measurement apparatus that serve to either provide heat to the system or absorb heat from the system). In SI system, heat energy is measured in joules (J). He is best known for his 1841 enunciation of one of the original statements of the conservation of energy (or what is now known as one of the first versions of the first law of thermodynamics): “Energy can be neither created nor destroyed. Values in parentheses are specific heats at a constant pressure of 1.00 atm. Calorimetry is used to measure amounts of heat transferred to or from a substance. If we use the metric system, the specific heat is the amount of heat that’s needed for a sample which weighs 1 kg to elevate its temperature by 1K.

He graduated from the University of California in 2010 with a degree in Computer Science. The temperature change, along with the specific heat and mass of the solution, can then be used to calculate the amount of heat involved in either case. Specific Heat is directly proportional to the mass of the object or substance, whereas heat capacity doesn’t depends upon the mass.
