WebSep 9, 2024 · Definition: The molar heat capacity of a substance is the quantity of heat required to raise the temperature of a molar amount of it by one degree. (I say "molar amount". In CGS calculations we use the mole – about 6 × 10 23 molecules. In SI calculations we use the kilomole – about 6 × 10 26 molecules.) Its SI unit is J kilomole −1 … WebIf you could keep shooting it with a photon of say energy 1 and you shot 10 of these photons and noticed that the substance had gained a temperature difference say from 25 to 26 ∘ C, then its specific heat capacity would be 10. (Specific heat capacity is more like a measure of the external energy given to produce the temperature change.) sleep and respiratory care update philips
