Is molar heat capacity a state function

Witryna13 cze 2024 · The heat capacity functions have a pivotal role in thermodynamics. We consider many of their properties further in the next section and in later chapters … Like the heat capacity of an object, the molar heat capacity of a substance may vary, sometimes substantially, depending on the starting temperature Tof the sample and the pressurePapplied to it. Therefore, it should be considered a function cm(P,T) of those two variables. Zobacz więcej The molar heat capacity of a chemical substance is the amount of energy that must be added, in the form of heat, to one mole of the substance in order to cause an increase of one unit in its temperature. Alternatively, it … Zobacz więcej The molar heat capacity of a substance, which may be denoted by cm, is the heat capacity C of a sample of the substance, divided by the amount (moles) n of the substance in the sample: cm where ΔQ is … Zobacz więcej Monatomic gases 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. Quantum mechanics predicts that, at room temperature … Zobacz więcej The SI unit of molar heat capacity heat is joule per kelvin per mole (J/(K⋅mol), J/(K mol), J K mol , etc.). 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 Celsius per mole (J/(°C⋅mol)).
