permeable
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.
A solid material with no crystal structure is called amorphous.
kidney, ureter, bladder, urethra
A substance that flows is called "liquid".
allow substances to diffuse through it it moves faster than a liquid with a relatively high viscosity
conductivity
it depends on the frequency of the current in question. the higher the frequency, the less depth in the cross-section the current flows. this is termed skin depth.
Depends on the material. The electricity can flow through metal better then it can through wood because wood is a conductor of electricity (example).
what type of material the pipe is made out of.
if the water flows through a material such as sand, the impurities get trapped and the water passes through.
Heat moves easily through materials with delocalised electrons, that is electrons which are free to move through the substance. This happens in metals and graphite.
Electricity flows through a light bulb and does not stay in it. Electric current is flowing electrons that has energy. When the electricity flows through some material, the properties of the material resists the flow. This causes the material to heat up and if it is thin and of the right type of material, it will glow. Think of it as a water pipe. When the pipe gets thinner, the water pressure builds up.

The Nile River flows through the Sahara and the Rio Grande flows through the Chihuahuan Desert.
The Nile flows through Egypt.
