The kinetic theory of molecules gives the idea about the movement and the behavior of the molecules in any different phase. The chemical reactivity of a particular molecule can be identified on the basis of kinetic theory of molecules. The phase of molecules changes and so changes it entropy ( movement of molecule in available space)
the building blocks of substances are called what atoms or molecules?
You question makes no sense. If particles dissolve they go into solution, they do not "break apart and scatter".
A mole is the unit of measurement based on Avogadro's number. It measures the number of atoms or molecules in a substance.
DIFFUSIBILITY The quality of being diffusible; capability of being poured or spread out.
This physical phenomenon (a change of phase) is called melting; during melting the chemical nature of molecules is not changed but the bonds between molecules are weakened.
Movement of molecules of a substance from its higher concentration towards its lower concentration by their own kinetic energy is called diffusion.
freedom of movement
Is Diffusion the movement of molecules from a greater to a lesser concentration.
When a charged body is placed close to a nonconducting substance, the molecules of the substance get polarised. This is called polarisation.
When a substance is heated, the extra energy makes the atoms and molecules in the substance vibrate faster and, in liquids and gases, move faster. A measure of the average velocity of such movement is called temperature. The effect of this increased movement is to change the structure of the substance. The regular order of the atoms or molecules of a solid breaks down to form a liquid - this is called melting. Further heating makes the atoms or molecules move so fast that the interactive forces between them are overcome, and they become gases - in which the atoms or molecules are free to move throughout their enclosing volume. This is called boiling or evaporation.
from an area of high concentration to an area of lower concentration.
It's called thermal energy, and it manifests itself as an increase of temperature.
Passive
Heat is defined as the movement of molecules in a substance. The lack of molecule movement occurs at a temperature of 0 degrees, Kelvin, or 'Absolute Zero'. Temperature is based on a set of equal steps called degrees. Degrees are a way to measure the level of heat in a substance.
Movement of molecules 4m higher to lower concentration is called osmosis
You think probable to molecules.
