To apply the theory, one considers the sample of the substance (solid, liquid, or gas) for which the specific heat capacity can be defined; in particular, ... See more 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, … See more 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 See more International system The SI unit for specific heat capacity is joule per kelvin per kilogram J/kg⋅K, J⋅K ⋅kg . Since an increment of temperature of one degree Celsius is the same as an increment of one kelvin, that is the same as joule per degree … See more Relation between specific heat capacities Starting from the fundamental thermodynamic relation one can show, where, See more 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 … See more The temperature of a sample of a substance reflects the average kinetic energy of its constituent particles (atoms or molecules) relative to its center of mass. However, not all energy provided to a sample of a substance will go into raising its … See more In theory, the specific heat capacity of a substance can also be derived from its abstract thermodynamic modeling by an equation of state and … See more http://physics.bu.edu/~duffy/py105/Heat.html

The specific heat is the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00 ºC. The specific heat c is a property of the substance; its SI unit is J/ (kg ⋅ K) or J/ (kg ⋅ °C ).
WebSpecific Heat for Ideal Gas. It has been demonstrated experimentally by Joule, that the internal energy is only a function of temperature ( T) i.e. u = u ( T) From enthalpy definition and ideal gas equation we have. h = u + P v P v = R T. therefore, h = u + R T = u ( T) + R T.
