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.
Why cant you change temperature and phase at the same time?
When an object is changing state form liquid to a gas the object is absorbing energy to allow its molecules to expand. it cant increase in temperature because it is using the energy that it is absorbing.

Are inorganic molecules large or small?
Even though the question is a little vague the answer is no. The specifics of carbon atoms allow them to form an almost endless variety of molecules among themselves or with the addition of other atoms (commonly hydrogen, oxygen, nitrogen etc.). That doesn't mean that there are no complex inorganic molecules (eg perovskites) but in general organic chemistry is more versatile and therefore rich and complex
Nuclear reactions change the composition of an atom's?
Nuclear reactions change the composition of an atom's nucleus, hence nuclear reaction.
How many Molecules are contained in 0.900 mol O2?
5.418E23 molecules
What is the function of Nuclear in a cell?
Nuclear pores allow molecules to move through the nuclear envelope.
What is a nuclear pores function in a cell?
Nuclear pores allow molecules to move through the nuclear envelope.
What selects which molecules enter the cell?
Nuclear decide and allow which molecules will be enter in the cell,- Isrg Rajan
What breaks down large molecules into smaller molecules?
nuclear explosions or bacteria
Can nuclear reactions create new molecules?
We don't generally think of nuclear reactions creating new molecules. A nuclear reaction is a reaction involving the nucleus of an atom (in the case of fission) or atoms (in the case of fusion). The manipulation or creation of new molecules is usually left in the domain of the science of chemistry, and not nuclear physics.
Does a nuclear change involve a change in molecules?
Yes!:)
Which molecules do not normally cross the nuclear membrane?
DNA
What is the membrane around the nucleus?
The nucleus is surrounded by a nuclear envelope composed of two membranes. The nuclear envelope is dotted with thousands of nuclear pores, which allow material to move into and out of the nucleus. Like messages, instructions, and blueprints moving in and out of a main office, a steady stream of proteins, RNA, and other molecules move through the nuclear pores to and from the rest of the cell. --Biology textbook
What is characteristic of nuclear envelope?
The nuclear membrane is a lipid bilayer. It has two layers of lipid molecules surrounding it.
What type of energy is produced by the movement of atom and molecules?
a nuclear
The energy stored in the bonds of molecules?
Chemical Energy
How does the nuclear envelope allow materials in and out of the envelope?
It does
