How do you xxplain Thermal conductivity of material?
part of that energy is the kinetic energy of these vibrations and moeements of particles
What can cause kinetic energy to change into thermal energy?
Friction can cause kinetic energy to change into thermal energy
Is metal strong?
Yes metal is generally strong.
What materials are flash light made from?
rubber because that is a good thermal insulator
How can you tell whether cavities in a casting are due to porosity or to shrinkage?
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.
Which has lowest thermal conductivity?
silica Aerogel Refer to the chart from the Wikipedia article on thermal conductivity in related links.
Is metal a thermal conductivity?
Yes, metal will conduct heat energy
Does copper possess high or low thermal conductivity?
Copper has a high thermal conductivity, not low. This is a good generalization of any metal, although they vary in conductivity.
What metal has the highest electrical and thermal conductivity of all?
Silver
What is the best thermal conductive metal?
This metal is silver with a thermal conductivity of 429 W/m.K at 27 0C.
Would glass iron wood or Styrofoam have the lowest thermal conductivity?
styrofoam
Which metal heat best?
The metal with the highest thermal conductivity is silver, followed by copper, then gold.
Do metal have poor thermal?
If you mean "thermal conductivity", no; metals are generally fairly good heat conductors.
Why does a metal spoon feel cooler than a piece of wood at 20C?
Because metal has better thermal conductivity than wood. Thermal conductivity depends of the atomic and molecular structure of the stuff. The air is a poor thermal conductor, but water is better.
Can silver conduct heat?
Silver has the highest thermal conductivity of any metal.
Is uranium conductible?
Thermal conductivity of uranium: 27 W/m.K. Electrical resistivity of uranium: 28.10-8 ohm.m.
Best metal heat transfer?
The metal with the best heat transfer is silver. Copper and aluminum hold second and third place in terms of thermal conductivity. The thermal conductivity of silver is 418 watts per meter Kelvin.
