2. Thermal conductivity and resistivity - Wikipedia

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

   The thermal conductivity of a material is a measure of its ability to conduct heat.It is commonly denoted by , , or and is measured in W·m −1 ·K −1.. Heat transfer occurs at a lower rate in materials of low thermal conductivity than in materials of high thermal conductivity.

3. Shape-memory polymer - Wikipedia

   en.wikipedia.org/wiki/Shape-memory_polymer

   Heating them activates their "memory". In the example of the dent, the fender could be repaired with a heat source, such as a hair-dryer. The impact results in a temporary form, which changes back to the original form upon heating—in effect, the plastic repairs itself.

4. Potassium hydroxide - Wikipedia

   en.wikipedia.org/wiki/Potassium_hydroxide

   Potassium hydroxide is an inorganic compound with the formula K OH, and is commonly called caustic potash.. Along with sodium hydroxide (NaOH), KOH is a prototypical strong base.

5. Thermal diffusivity - Wikipedia

   en.wikipedia.org/wiki/Thermal_diffusivity

   It is a measure of the rate of heat transfer inside a material and has SI units of m 2 /s. It is an intensive property . Thermal diffusivity is usually denoted by lowercase alpha ( α ), but a , h , κ ( kappa ), [ 2 ] K , [ 3 ] , D , D T {\displaystyle D_{T}} are also used.

6. Newton's law of cooling - Wikipedia

   en.wikipedia.org/wiki/Newton's_law_of_cooling

   The statement of Newton's law used in the heat transfer literature puts into mathematics the idea that the rate of heat loss of a body is proportional to the difference in temperatures between the body and its surroundings. For a temperature-independent heat transfer coefficient, the statement is:

7. Annealing (materials science) - Wikipedia

   en.wikipedia.org/wiki/Annealing_(materials_science)

   With knowledge of the composition and phase diagram, heat treatment can be used to adjust from harder and more brittle to softer and more ductile. In the case of ferrous metals, such as steel, annealing is performed by heating the material (generally until glowing) for a while and then slowly letting it cool to room temperature in still air.
