Someone wrote "water". Styrofoam is much lower. If you have a foam cup of hot water and stick your finger in the water, you feel lots of heat. If you hold the cup, you feel far less heat. One of the keys to the low thermal conductivity of foam is that it's mostly just some gas, maybe air or nitrogen, with a support structure of polystyrene or some other plastic type material. Gases are not good conductors of heat.

∙ 13y agoThe least permeable rocks are those which contain very fine particles such as shale, because there is very little space within their particles to let water through. This is important within the oil industry as shale is often a 'cap rock' and so prevents the oil escaping, leaving it for us to find and use.

Difference between porosity and permeability?
Porosity is the amount of void space in a rock or other earth material (like a sand deposit) - in other words, it´s how much water a material can hold. Permeability refers to how well water flows through a material - that´s controlled by how large the pores are, and how well connected they are.
What is permeability value of germanium?
16.0 is the value of permeability
The material with the lowest density among those listed is?
But you have not presented us with any list.
What is Relative Permeability of stainless steel?
The Relative Permeability of stainless steel is approximately 1. This is applicable to stainless steel with no or hardly any magnetic property.
Which material has the least melting point?
Helium remains liquid even at absolute zero, so by default it has the lowest melting point. If the material must actually freeze, the material is therefore Hydrogen. BOOMSHEDANGA! (Like my new catchphrase?)
What is the ability of a cell membrane to allow material to pass through it called?
permeability
What is the numerical value of the actual mks permeability of the core material?
µr= relative permeability; µ=material of interest; µo= actual permeability µr=µ/µo
If a material has a high conductivity does it have a high permeability and if so what would be an approximate permeability for the high conductive material?

The permeability of a material is 0.998is?
it is diamagnetic
What material has a relative permeability of one?
vacuum
In science what does permeability refer to?
It has meanings in both electromagnetism and chemistry/earth sciences. Permeability in electromagnetism in means how receptive a material is to magnetization. Permeability in earth sciences can mean how well a material such as rock can transmit fluids.
What is permeability?
Characteristic of a material that is full of tiny connected airspace that water can seep through.
What is permeability in electromagnetism?
Permeability is the measure of the ability of a material to support the formation of a magnetic field within itself.(Degree of magnetization that a material obtains in response to an applied magnetic field.) It is represented by the Greek letter μ.
A magnetic material has a relative permeability of 10000 what does this mean?
The relative permeability of 10,000 means that the material can support a magnetic field 10,000 times more dense than than a magnetic field in free space.
What is meant by magnetic permeability?
All materials are magnetized when placed in the magnetic field . The material magnetized by the effect of a magnetic field is called magnetic permeability.
What is aquatard?
A material of low permeability that greatly slows the movement of ground water.
What material should have high electro magnetic property?
A material with high initial permeability and low retentivity have electromagnetic property.
