Is the heating of iron III oxide for sometime a physical or chemical change?
Just heating the metal would be a physical change, as you would only have a warmer iron III oxide. However, if the heat caused a reaction, it would then be a chemical change.
How heating a bar magnet would change its magnetic field?

CHEMICAL:)
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?

Would the sugar change take place without heating?
Heating sugar it is thermally degraded. But sugar can be modified also by other chemical reactions.
Do solutes on each side of the membrane change over time?
Maybe, maybe not. You would need to specify the nature of the solutes, the permeability of the membrane to each, and the pressures involved.
How is permeability related to the size of the grains that make up the sediment?
If the size of the sediment is very small then it would have poor permeability But if the size of the sediment was large then it would be easier for liquids to flow through.
How does heating a gas in a rigid container change its pressure?
Heating a gas in a closed container would increase it's pressure. This would happen because when you heat the gas, the particles' kinetic energy increases, making them move faster, and more. They will hit the sides of the container and create pressure.
What is High permeability vs low permeability?
Permittivity (ε) applies to electric fields, and permeability (μ) refers to magnetic fields.In electromagnetism, permeability is the measure of the ability of a material to support the formation of a magnetic field within itself AND permittivity is the measure of how much resistance is encountered when forming an electric field in a medium.Also their relation is given byv= 1----1/2(ε*μ)v=velocity of light.
