Definition of heat capacity in US English:

heat capacity


  • The number of heat units needed to raise the temperature of a body by one degree.

    • ‘Since temperature is just the average kinetic energy of atoms, the heat capacity per unit volume is dependant on the number of atoms per unit volume.’
    • ‘It was clear that the shape of all these peaks was unsymmetrical and the heat capacity changed more rapidly in the higher temperature side.’
    • ‘Because of similarities in heat capacity, density, and other physical properties, the welding characteristics of the alloys described in this article are quite similar to certain stainless steels.’
    • ‘This assumption is most likely not valid for DNA, where the melting is accompanied by a significant heat capacity increase.’
    • ‘Land has a different thermal response because the heated layer is thin and its heat capacity is small.’
    • ‘The amount of heat involved in the reaction is determined as above by measuring the temperature change of the surrounding medium and multiplying by the heat capacity of the medium.’
    • ‘‘Very, very, very hot,’ said our waitress, astutely measuring our heat capacity.’
    • ‘At the melting temperature, the heat capacity reaches a maximum.’
    • ‘Just as a side note, this scattering should also depend on the heat capacity of the samples, since the fluctuations in state depend on the heat capacity.’
    • ‘If the heating takes place at constant pressure, the heat capacity must include the work contribution.’
    • ‘In other words, water vapor has a low heat capacity and poor thermal conduction.’
    • ‘However, one small difference exists: biodiesel has a higher heat capacity than regular diesel - it burns at a higher temperature - so it needs to warm up longer before use than regular diesel does.’
    • ‘But even very hot coals with a high heat capacity can be walked over without getting burned if one's feet are insulated, e.g., with a liquid such as sweat or water.’
    • ‘The heat capacity of the top three meters of the ocean is equal to that of the entire atmosphere, but everyone knows the ocean is more than three meters deep.’
    • ‘With the large heat capacity of wet soil, plants will only be exposed to significant changes in temperature if, for example, a heavy rainfall changes soil temperature.’
    • ‘We have shown that, in the presence of cholesterol, the relaxation times change to the same degree as the heat capacity.’
    • ‘Specific heat capacity is something like energy density of a substance, and measures how much energy must be contained in a substance for it to have a certain temperature.’
    • ‘The rest is absorbed by the ground and by the oceans, which play a key role in the energy budget due to their large heat capacity and their ability to store carbon dioxide, and, of course, water vapour.’
    • ‘Such an influence has been proposed from measurements of the heat capacity.’
