  2. Calorimeter - Wikipedia

    en.wikipedia.org/wiki/Calorimeter

    Dividing the energy change by how many moles of A were present gives its enthalpy change of reaction. q = C v ( T f − T i ) {\displaystyle q=C_{\text{v}}(T_{f}-T_{i})} where q is the amount of heat according to the change in temperature measured in joules and C v is the heat capacity of the calorimeter which is a value associated with each ...

    An ideal gas barometer may be constructed by mechanically connecting an ideal gas to the system being measured, while thermally insulating it. The volume will then measure pressure, by the ideal gas equation P = NkT/V. Calorimeter – a device which measures the heat energy added to a system. [4]

  4. Heat meter - Wikipedia

    en.wikipedia.org/wiki/Heat_meter

    A heat meter, thermal energy meter or energy meter is a device which measures thermal energy provided by a source or delivered to a sink, by measuring the flow rate of the heat transfer fluid and the change in its temperature between the outflow and return legs of the system.

  5. Calorimetry - Wikipedia

    en.wikipedia.org/wiki/Calorimetry

    Calorimetry requires that a reference material that changes temperature have known definite thermal constitutive properties. The classical rule, recognized by Clausius and Kelvin, is that the pressure exerted by the calorimetric material is fully and rapidly determined solely by its temperature and volume; this rule is for changes that do not involve phase change, such as melting of ice.

    Processes transferring energy from a non-thermal carrier to heat as a carrier do produce entropy (Example: mechanical/electrical friction, established by Count Rumford). Either the produced entropy or heat are measured (calorimetry) or the transferred energy of the non-thermal carrier may be measured. calorimeter

    en.wikipedia.org/wiki/Thermal_analysis

    Polymers represent another large area in which thermal analysis finds strong applications. Thermoplastic polymers are commonly found in everyday packaging and household items, but for the analysis of the raw materials, effects of the many additive used (including stabilisers and colours) and fine-tuning of the moulding or extrusion processing used can be achieved by using differential scanning ...

  9. Thermal energy storage - Wikipedia

    en.wikipedia.org/wiki/Thermal_energy_storage

    Thermal energy storage (TES) is the storage of thermal energy for later reuse. Employing widely different technologies, it allows surplus thermal energy to be stored for hours, days, or months. Scale both of storage and use vary from small to large – from individual processes to district, town, or region.
