Heat concentration
In thermodynamics, the specific heat capacity (symbol c) of a substance is the heat capacity of a sample of the substance divided by the mass of the sample, also sometimes referred to as massic heat capacity. Informally, it is the amount of heat that must be added to one unit of mass of the substance in order to … Ver más The specific heat capacity of a substance, usually denoted by $${\displaystyle c}$$ or s, is the heat capacity $${\displaystyle C}$$ of a sample of the substance, divided by the mass $${\displaystyle M}$$ of the sample: Ver más The specific heat capacity of a substance is typically determined according to the definition; namely, by measuring the heat capacity of a sample of the substance, usually with a calorimeter, and dividing by the sample's mass. Several techniques can be applied for … Ver más Relation between specific heat capacities Starting from the fundamental thermodynamic relation one can show, Ver más In theory, the specific heat capacity of a substance can also be derived from its abstract thermodynamic modeling by an equation of state and an internal energy function. Ver más International system The SI unit for specific heat capacity is joule per kelvin per kilogram J/kg⋅K, J⋅K ⋅kg .
