Do not soak temperature sensors for long periods of time, particularly at temperatures where oxidation is likely to occur. Do not pull or overly strain the temperature sensor cable. If a temperature sensor requires annealing, use recommended temperatures and techniques. Afterwards, always verify ...
Running hot water over the metal lid of a glass jar makes it easier to open the jar. Why? Discuss two other practical examples based on matter and/or heat concepts. Physics explains thermal expansion as linear dimensions increasing by the same percentage with an increase in temperature. In ot...
These superalloys, which contain 15–60% iron and 25–45% nickel, are used inblades, discs and engine casingsthat require low thermal expansion properties. Cobalt superalloys are used in jet engine components that require excellent corrosion resistance against hot combustion gases. What is the large...
I show that the hottest pile of burning fuel occurs when the height of the pile is roughly the same as its base diameter. Future studies may address the shape effect of wind, material type, and packing. Key is why humans of all eras have been relying on this design of fire "...
Creep is a permanent deformation that occurs due to long term exposure to high levels of stress below the yield strength of the materials in the joint. It is more severe in high-temperature applications. Relaxation is when the microstructure in the materials of a joint restructure, converting ex...

Thermal Expansion & Heat Transfer from Chapter 17 / Lesson 12 25K Thermal expansion and heat transfer affect materials based on a given temperature. Learn how to calculate the rate of heat transfer, discover the importance of understanding thermal expansion...
The thermosalient effect occurs between two structures known as α and γ modifications. When PHA transforms from one structure into another between approx. 70 and 80 degrees Celsius (158 to 176 degrees Fahrenheit), the crystals drastically expand in one direction. And this is where PHA is likel...
The shaking that occurs when magma moves beneath the surface is called a. columnar vibrations. b. basalt accumulation. c. volcanic tremor. d. cratering. e. fissure eruption. What do you understand by the free convection boundary layer and how does it affect heat transf...
(cracking/breaking) of glass pipes over time. It is exponentially more prone to failure where the glass is constantly expanded and contracted by heat. Most notably this occurs at the bottom of the bowl where heat is concentrated during the lighting of tobacco, and is precisely where importers ...
