2. Araldite - Wikipedia

   en.wikipedia.org/wiki/Araldite

   The first batches of Araldite epoxy resins, for which the brand is best known, were made in Duxford, England in 1950. [1] Araldite adhesive sets by the interaction of an epoxy resin with a hardener. Mixing an epoxy resin and hardener together starts a chemical reaction that produces heat – an exothermic reaction.

3. Thermal conductance and resistance - Wikipedia

   en.wikipedia.org/wiki/Thermal_conductance_and...

   The SI unit of absolute thermal resistance is kelvins per watt (K/W) or the equivalent degrees Celsius per watt (°C/W) – the two are the same since the intervals are equal: ΔT = 1 K = 1 °C. The thermal resistance of materials is of great interest to electronic engineers because most electrical components generate heat and need to be cooled.

4. Thermal conductivity and resistivity - Wikipedia

   en.wikipedia.org/wiki/Thermal_conductivity_and...

   The construction industry makes use of measures such as the R-value (resistance) and the U-value (transmittance or conductance). Although related to the thermal conductivity of a material used in an insulation product or assembly, R- and U-values are measured per unit area, and depend on the specified thickness of the product or assembly.

5. Tensiometer (surface tension) - Wikipedia

   en.wikipedia.org/wiki/Tensiometer_(surface_tension)

   In surface science, a tensiometer is a measuring instrument used to measure the surface tension (γ) of liquids or surfaces.Tensiometers are used in research and development laboratories to determine the surface tension of liquids like coatings, lacquers or adhesives.

6. Resistance thermometer - Wikipedia

   en.wikipedia.org/wiki/Resistance_thermometer

   Copper has a very linear resistance–temperature relationship; however, copper oxidizes at moderate temperatures and cannot be used over 150 °C (302 °F). [citation needed] The significant characteristic of metals used as resistive elements is the linear approximation of the resistance versus temperature relationship between 0 and 100 °C.

7. List of thermal conductivities - Wikipedia

   en.wikipedia.org/wiki/List_of_thermal_conductivities

   Small granite pillars have failed under loads that averaged out to about 1.43 ⋅ 10 8 Newtons/meter 2 and this kind of rock has a sonic speed of about 5.6 ± 0.3 ⋅ 10 3 m/sec (stp), a density of about 2.7 g/cm 3 and specific heat ranging from about 0.2 to 0.3 cal/g °C through the temperature interval 100-1000 °C [Stowe pages 41 & 59 and ...

8. Temperature measurement - Wikipedia

   en.wikipedia.org/wiki/Temperature_measurement

   A medical/clinical thermometer showing the temperature of 101.7 °F (38.7 °C) Temperature measurement (also known as thermometry) describes the process of measuring a current temperature for immediate or later evaluation. Datasets consisting of repeated standardized measurements can be used to assess temperature trends.

9. Hot-melt adhesive - Wikipedia

   en.wikipedia.org/wiki/Hot-melt_adhesive

   The bonding temperature is lower than with most other HMAs, only about 50 °C (122 °F) to 70 °C (158 °F), when the adhesive behaves as a soft rubber acting as a pressure-sensitive adhesive. The surface wetting in this amorphous state is good, and on cooling the polymer crystallizes, forming a strong flexible bond with high cohesion.
