What else can I help you with?
I have a science experiment to do. How do you do a sponge absorbency project?
Oh that's quite simple. Find a sponge and get a bowl. Put the sponge in the water and explain how the pores in the sponge suck in the water as you put pressure on it. As you squeeze it explain that the pores release the water through them.
How do impermeable surfaces affect infiltration?
A rock that has high porosity is not permeable if the pores or fractures are not connected. The larger and better shorted the particles are, the more permeable the rock or sediment tends to be. Because of this characteristic composition, clay is essentially impermeable, which means that water cannot flow through it.
Why is Styrofoam a good insulator?
Styrofoam is a very porous material; air from the closed pores has a bad thermal conductivity.
What are cell membrane pores are made of?
Cell membrane pores are made up of protein.
How do material leave the nucleus?
Both plant cells and animal cells have a nuclues.The nucleus of both plant and animal cells have pores on their double membrane.These pores allow the nucleus to communicate with the outside environment that is the cytoplasm.This can be through sending of substances into the nucleus.For example mRNA. However there are times when the materials are very big than the pore.In this case energy which is normally ATP combines with the substance to force it to penetrate.
Would an impermeable material have large or small pores Would the pores be connected or unconnected?
An impermeable material would have small pores, if any, that are likely unconnected. Small pores limit the movement of substances through the material, and unconnected pores minimize the pathways for substances to traverse.
Would an impermeable material have small or large pores?
Small pores
How can a material be porous but also impermeable?
A material can be porous but also impermeable due to its surface structure. The molecular level can allow molecules of air to pass through, but not water molecules.many materials, such as GoreTex, has a surface structure, that at a molecular level can allow molecules of air to pass thru but not molecules of water. This way, you can be protected from falling rain, but also have a material that will "breathe" and wont keep you feeling muggy inside.
Examples of permeable and impermeable rocks?
Permeable rocks: sandstone, limestone, and conglomerate. These rocks have interconnected pores that allow water and other fluids to flow through them. Impermeable rocks: granite, basalt, and shale. These rocks have very few or no pores, making them resistant to the movement of water and fluids.
Water cannot pass through solid rock because it is?
Impermeable. The pores in solid rock are too small for water to flow through.
What is the material in facial pores?
Sebum
Two factors that determine the porosity material?
The two factors that determine the porosity of a material are the size and distribution of the pores within the material. Larger pores and a more interconnected network of pores typically result in higher porosity. Additionally, the material's density and composition also play a role in determining its overall porosity.
What are permeable and impermeable rocks?
Permeability is a measure of how well a porous media transmits a fluid. It has nothing to do with the fluid itself. It is measure in (length)2. The Hydraulic Conductivity is a measure of how easily water moves through the porous media. It depends on the permeability of the matrix, but also is a function of the fluid. It is a measure of (length)/(time)

Is water absorbed in the pores?
Yes, water can be absorbed into the pores of certain materials like soil, rocks, and ceramics. The amount of water absorbed will depend on the size and structure of the pores, as well as the surface properties of the material.

How does absorbancy work?
The fluid just settles in the pores (air pockets/holes)of the material.
