first lets clarify what is matter. in its general use, matter is everything that is not virtual. example of virtual things : mathematics, ideas, philosophy...
Even "light" is matter as it can be attracted by gravity.
So, this is what matter is, its made of something.
lets go with the other part of your question.
Matter can be found basically in 3 phases (lets put aside the 4th phase: plasma)
solid, liquid, gases.
in a solid, molecules can only vibrate.
in a liquid, molecules can vibrate and rotate on each other
in a gas, molecules can vibrate, rotate and slide
(see link)
this is how matter behave.
If you want to know what happen when you mix stuff like salt in water, then this has to do with solubility, size of particle and interstice. see link for in depth explanation on "solubility".
it dissociates
it melts
it acts as a weak acid.
In high solute concentrations water will flow out of the cell. In low solute concentrations water will flow into the cell.
Not all substances behave the same way when mixed with water. Some substances dissolve in water to form a solution, while others may react with water to form new compounds or stay separate as a suspension or colloid. The behavior of a substance in water depends on its chemical properties and the interactions between its molecules and water molecules.
as a photon
Electric charges behave as a matter and it contains three building blocks of matter, they are :electrons, protons and neutrons of which two are electrically charge
I know that particles in matter move a lot but i not quite sure what it means
they dont behave in small or large places because they only behave in the water
Law Of Nature
it dissociates
it melts
The generalization about predictable ways in which matter and energy behave is called a scientific law. Scientific laws describe observed phenomena and are based on repeated experimental observations.
When no Air D or destractions in the water .
No matter if the boss is present or absent. Do your duty!
Oxygen in water exists as dissolved oxygen molecules, which are crucial for aquatic organisms to survive. Oxygen can be absorbed into water through diffusion from the atmosphere or by photosynthesis from aquatic plants. The level of dissolved oxygen in water is influenced by factors like temperature, pressure, and the presence of organic matter.
it acts as a weak acid.
