  2. Heat capacity - Wikipedia

    en.wikipedia.org/wiki/Heat_capacity

    Heat capacity or thermal capacity is a physical ... For example, the heat capacity of a block of iron weighing one pound is about 204 J/K when measured from a ...

  3. Specific heat capacity - Wikipedia

    en.wikipedia.org/wiki/Specific_heat_capacity

    For example, the heat required to raise the temperature of 1 kg of water by 1 K is 4184 joules, so the specific heat capacity of water is 4184 J⋅kg −1 ⋅K −1. [3] Specific heat capacity often varies with temperature, and is different for each state of matter.

  4. Table of specific heat capacities - Wikipedia

    en.wikipedia.org/wiki/Table_of_specific_heat...

    For example, Paraffin has very large molecules and thus a high heat capacity per mole, but as a substance it does not have remarkable heat capacity in terms of volume, mass, or atom-mol (which is just 1.41 R per mole of atoms, or less than half of most solids, in terms of heat capacity per atom).

  5. Intensive and extensive properties - Wikipedia

    en.wikipedia.org/wiki/Intensive_and_extensive...

    For example, heat capacity is an extensive property of a system. Dividing heat capacity, , by the mass of the system gives the specific heat capacity, , which is an intensive property. When the extensive property is represented by an upper-case letter, the symbol for the corresponding intensive property is usually represented by a lower-case ...

  6. Thermal energy storage - Wikipedia

    en.wikipedia.org/wiki/Thermal_energy_storage

    Since a phase change is not needed many more materials are available for use in an encapsulated thermal battery. One of the key properties of an encapsulated thermal battery is its volumetric heat capacity (VHC), also termed volume-specific heat capacity. Several substances are used for these thermal batteries, for example water, concrete, and ...

  7. Thermal mass - Wikipedia

    en.wikipedia.org/wiki/Thermal_mass

    For example, if 250 J of heat energy is added to a copper gear with a thermal mass of 38.46 J/°C, its temperature will rise by 6.50 °C. If the body consists of a homogeneous material with sufficiently known physical properties, the thermal mass is simply the mass of material present times the specific heat capacity of that material.

  8. Heat - Wikipedia

    en.wikipedia.org/wiki/Heat

    Heat capacity is a measurable physical quantity equal to the ratio of the heat added to an object to the resulting temperature change. [76] The molar heat capacity is the heat capacity per unit amount (SI unit: mole) of a pure substance, and the specific heat capacity, often called simply specific heat, is the heat capacity per unit mass of a ...

  9. Heat equation - Wikipedia

    en.wikipedia.org/wiki/Heat_equation

    The heat equation is the prototypical example of a parabolic partial differential equation. Using the Laplace operator , the heat equation can be simplified, and generalized to similar equations over spaces of arbitrary number of dimensions, as
