How does a molecule turn into a noticably tangible thing

Click For Summary

Discussion Overview

The discussion revolves around the transition of molecules to tangible objects, exploring how individual molecules aggregate to form visible matter. Participants examine the nature of molecular interactions in liquids and solids, and the conditions under which collections of molecules become noticeable to the human eye.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions how a single molecule can be increased in size to become visible, particularly in the context of liquids like water and solids.
  • Another participant introduces the concept of "aggregation" and "bulk properties" as relevant to the discussion.
  • A participant states that in liquids, molecules are simply piled on top of each other, while in solids, they are bonded together rigidly.
  • Intermolecular forces are mentioned as a key factor in how molecules stick together, with a suggestion to look into network covalent bonding.
  • One participant challenges the notion that solid objects cannot be made of a single type of molecule, citing table salt as an example and questioning the distinction between molecules and atoms.
  • A later reply emphasizes that large collections of molecules can scatter or absorb light in a way that makes them noticeable, contrasting with single molecules that do not.
  • Another participant reiterates the point about table salt being a solid made of a single type of molecule, while also correcting a typographical error regarding the abbreviation STP.
  • One participant suggests that a crystal can be viewed as a large molecule, specifically in the context of sodium chloride, where sodium and chlorine atoms bond together extensively.
  • Another participant notes that certain polymers can be structured such that a single object may consist of one large molecule.

Areas of Agreement / Disagreement

Participants express differing views on the nature of solid objects and the definition of molecules versus atoms. There is no consensus on how to define or conceptualize the transition from molecules to tangible objects, and multiple competing perspectives are presented.

Contextual Notes

Some statements rely on specific definitions of terms like "molecule" and "solid," which may not be universally agreed upon. The discussion also touches on the complexities of molecular bonding and aggregation without resolving these nuances.

Firstly, i know this question is worded strangely, i wrote noticeably tangible because a molecule is a tangible thing but not visible to the eye without equipment. But my question is, how do we get a single molecule, and increase its size to be visible? For example a cup of water is like a collection of many water molecules. Are these molecules combing with each other or just near each other? What about a solid object? I can't think of any solid objects that are made of a single type of molecule off the top of my head...

I guess to kind of simplify my question. Do collections of the same molecule combine with each other or stack on top of each other? Or something else?

See "aggregation," or "bulk properties."

Water is a liquid and liquids are literally just individual molecules piled on top of each other. In solids, the molecules are rigidly bonded together.

Intermolecular forces are what makes molecules stick together. Also google for network covalent bonding.

Why not? Table salt is a sold at STP, and it is made up of a single type of molecule. Are you confusing molecules with atoms? Even then, gold is a solid, and it is made up of a single type of atom.
 
You may not notice a single gnat flying around, but you sure would notice 6.02x10^23 of them!

Similarly, single molecules will absorb or scatter very small amounts of light that are undetectable by the human eye. Large collections of these molecules, however, will scatter or absorb enough light to be noticeable by us.

Many, MANY molecules collected near enough to each other become tangible.

(Note: Table Salt is Sodium Chloride. STP is Sodium Triphosphate. Better name, Sodium Tripolyphosphate; )

STP means standard temperature and pressure.

I did not see earlier. "sold" was meant to be "solid"; "at" was not understood but misunderstood for "as".

My bad, I can't see or type well :smile:

What is a single molecule in a crystal? A crystal can be thought of as a really big molecule.
For something such as a NaCl ( table salt ) one can think all the atoms of sodium and all the atoms of chlorine as bonding together into one really big molecule. After all, each Na is bonded to all the chlorine atoms around it, and in turn each chlorine atom is bonded to all the sodium atoms surrounding it.
The unit Na-Cl is just the smallest representation of those atoms, and gives the molecular formula of table salt.

When an object is made out of a polymer, the single object may be a one single molecule, if you have the right type of polymer for which this is true.
