part of that energy is the kinetic energy of these vibrations and moeements of particles
Friction can cause kinetic energy to change into thermal energy
Yes metal is generally strong.
Porosity is a defect, which results from air entrapment in the molten metal due to turbulent flow causing air bubbles. Usually, this defect is characterized by smooth and spherical pores, but if rough and angular it is most likely as a result of shrinkage dendrites. The mechanical properties associated with shrinkage is the thermal expansion of the molten metal when it solidifies and cools to room temperature, if the riser isn't properly designed to accommodate shrinkage, there would be dimensional changes and are usually in form of cracks.
rubber because that is a good thermal insulator
silica Aerogel Refer to the chart from the Wikipedia article on thermal conductivity in related links.
Yes, metal generally has high thermal conductivity compared to other materials.
Yes, metal will conduct heat energy
Copper has a high thermal conductivity, not low. This is a good generalization of any metal, although they vary in conductivity.
Silver
The metal with the highest thermal conductivity is silver, followed by copper, then gold.
Argon gas has low electrical conductivity, as it is classified as a non-metal gas. However, it has good thermal conductivity, which means it efficiently transfers heat.
If you mean "thermal conductivity", no; metals are generally fairly good heat conductors.
Thermal conductivity of uranium: 27 W/m.K. Electrical resistivity of uranium: 28.10-8 ohm.m.
Copper is known for its high thermal conductivity, making it one of the best options for efficient heat transfer in various applications. Other metals like silver and gold also have high thermal conductivity but are less commonly used due to their higher cost.
More Thermal Conductivity
Styrofoam would have the lowest thermal conductivity among these materials. It is a good insulator because it is made up of mostly trapped air bubbles that restrict the transfer of heat. Glass, iron, and wood have higher thermal conductivities compared to Styrofoam.
