Pressure is a statistical mechanic variable, representing the force exerted on a unit surface by a body that is composed by a huge number of particles, sufficiently great to apply statistical methods to average the fluctuating force exerted in time due to the interaction of individual particles with the surface.
A molecule is not composed by a sufficient number of particle generally, and, more important, the chemical bonds composing it gives to the molecule an ordered structure, so that pressure cannot be rigorously defined talking about molecules.
In some application, when dealing with solutions of very big molecules, like proteins or polymers chains, the interaction of these big molecules with the solvent, for example water, is modelled as the interaction of a body constituted by several rigid sphere bonded together (the molecule) with a continuous background medium (the solvent). This approximation, that is called implicit solvent approximation, is allowed by the fact that the solvent molecules are much smaller than the solute molecules. In this context it is possible to say that the solvent exert a pressure on the molecule surface, that naturally depends on many parameters like temperature, density of the solution, and so on, besides the nature of solvent and solute.
This is however a simpling model, that is used only because frequently a fully molecular model, where both solvent and solute are represented as molecules populations, is too hard to be solved.

What is the high pressure area of tightly packed molecules?
Rarefaction
Is a low pressure area of loosely packed molecules?
Compression
Which soil is safest to build a structure in earthquake prone area?
very tightly packed soil and not on mud or fill. you should build on bedrock
Why do solids lack the property of diffusion?
Because diffusion involves the random movement of particles. In a solid, particles cannot move to an area of low concentration as the intermolecular forces are too great. So the particles stay tightly packed in a solid.

What is the high pressure area of tightly packed molecules?
Rarefaction
What do you call an area of tightly packed molecules?
I think it's polymer... Because "poly" means many and "mer" means units. Yeah, I'm pretty sure it's polymer.
What is a low pressure area of loosely packed molecules?
Compression
Is a low pressure area of loosely packed molecules?
Compression
Is rarefaction a high pressure area of tightly packed molecules?
No. A rarefaction is the region of a sound wave where the particles are spread out rather than close together. The closer together regions are compressions. These terms are used about waves in air, not weather systems.
How tightly packed the magnetic lines tells us?
The closer the magnetic field lines, the stronger the magnetic force in that area.
Which soil is safest to build a structure in earthquake prone area?
very tightly packed soil and not on mud or fill. you should build on bedrock
Is a vascular tissue made up of tightly packed cells that make up the internal linings of some animals?
Endothelial cells form the vascular network but acquire very different characteristics depending on their location. In the brain, endothelial cells are tightly packed to provide the brain-blood barrier that protects the brain from blood toxins. In the endocrine gland, endothelial cells are leaky and cause fenestrations to allow hormone trafficking throughout the body. In general, how tightly packed vascular network cells are depends on which area they are located.
Where do deers sleep?
Whitetail deer ussualy tend to bed in thick brush or an area where trees are tightly packed. Also, where the area is rarley disturbed and gives some protection from elements. (trees,brush)
Why the particales in solids are tightly packed?
Because only the particles are packed together like that the solid can have define shape and volume. If they not packed together that are liquid.So we can use this point (the particles are packed together) to know what is that? Solid, Liquid or Gas. ---- The particles of a solid are packed tightly together, the particles of a liquid can move around but are still touching each other, and the particles in a gas are free to wizz around.
Why is non metal densities greater than metal densities?
the atoms are very tightly packed together as there are strong forces of attraction
What is the meaning of densely?
Densely means closely compacted together, with little space in between. It can refer to objects or substances that are tightly packed together in a given area.
