How would you explain the terms ductility and thermal conductivity mean?
Ductility: the ability of a metal to be easily transformed in wires.Heat conductivity: the ability of a material to conduct heat.
Explain what the terms ductility and thermal conductivity mean?
a) High ductility means that the metal can be drawn (pulled) to form a wire. Thermal conductivity tells us how easily heat is conducted through a standard area of metal. b) Useful in forming copper wire which is used to conduct electricity. c) Metal handles of cooking utensils can become hot. Plastic or wood have low thermal conductivity, and thus the end held by the user can be much cooler than the end of a metal handle would be.
What does thermal conductivity mean?
A thermal conductor allows heat to readily flow through itself. An example of a material with a low thermal conductivity would be air, and an example of a material with a high thermal conductivity would be steel.
Will a styrofoam cup float or sink in water?
They would float.
What would happen if you put a block of Styrofoam into water?
It floats.
What does thermal conductors mean?
A thermal conductor allows heat to readily flow through itself. An example of a material with a low thermal conductivity would be air, and an example of a material with a high thermal conductivity would be steel.
What is the scientific name of styrofoam?
Styrofoam doesn't have a scientific name, since it is an object, but the closest would be it's official name, polystyrene thermal insulation material.
Why conductivity of diamond is highest being a nonmetal?
It would help if you specify whether you are talking about thermal conductivity, or electrical conductivity. Diamond certainly doesn't has the highest electrical conductivity. Its thermal conductivity is one of the highest known, and - if a synthetic diamond is made from pure (99.9%) C-12, it is indeed the highest. The Wikipedia article attributes this to a strong covalent bonding.

Does thermal conductivity play a role in the development of residual stresses in metal?
Answer In most applications, I would not expect Thermal conductivity to be a factor. Only in applications where the part is exposed to extreme heat or cold or large fluctuations in temperatures under loads.
What material has high thermal conductivity but low electrical conductivity?
Someone wrote "what material has the highest R-value". This answer is not conducive to progress in their learning. The "r" in R-value stands for Resistance, that is, resistance to flow of heat. Conductivity is the reciprocal, or inverse, of the Resistivity. "Thermal Conductivity" is transfer of Heat. Since Heat is ultimately the jiggling around of small bits of Matter (fundamental particles like electrons, protons and neutrons), then atoms (assemblages of these 3 fundamental particles), then molecules (assemblages of similar or dissimilar atoms), or also the jiggling around of atoms within molecules) - then the material with the highest Resistivity would be the Absence of Matter, this is, Vacuum (not quite a material, strictly speaking, but "found" between the walls of a vacuum, or "Dewar", flask). For the material with (possibly) the lowest Resistivity, or highest Conductivity, try the Wikipedia article on "Thermal Conductivity". If you're a girl, it may be your best friend.
Would a light meter tell if a stone is an antique European cut diamond?
I think you are referring to the 'thermal diamond tester or thermal probe' (instead of light meter) but it will work on any cut. It tests the thermal conductivity of the material, so the cut does not matter or affect it. Thermal probe is not a confirmatory testing device to separate diamond from synthetic mossanite. Synthetic moissanite which has a thermal conductivity very similar to diamond and as a result gives the same reaction to the thermal testers, as diamond. Even highly included diamonds may give false readings.

What substances would be good conductors of heat?
Substances with high thermal conductivity are generally good conductors of heat. Some examples include metals such as copper, aluminum, and silver. Additionally, materials like diamond and graphite also exhibit high thermal conductivity.
Does helium conduct heat or electricity?
thermal conductivity of gas is directly proportional to mean free path, mean particle speed and heat capacity. Due to small size and lower mass, helium has high mean free path and mean particle speed; hence has high thermal conductivity.
What does thermal conductivity mean?
A thermal conductor allows heat to readily flow through itself. An example of a material with a low thermal conductivity would be air, and an example of a material with a high thermal conductivity would be steel.
How long does it take styrofoam to digest?
Styrofoam is not digestible. The body will eliminate it before it would be digestible. Styrofoam should not be consumed under any circumstances.
