Question

What are the characteristics of molecules of a substance?​

Answer 1

Explanation:

The three main properties of a molecular substance include: low melting points, or a temperature that indicates when a solid substance changes to a liquid; and boiling points, or a temperature that indicates the point at which a liquid changes to a gas, or vapor; poor conductivity; and low solubility,

Answer 2

Answer:

$\huge\fbox\colorbox{lime}{answer}$

All molecules have a definite mass and size that are dependent on the atoms from which the molecule is made. The mass is equal to the sum of the masses of all the individual atoms in the molecular structure. The size is not only dependent on the atomic components of the molecule, but also on the arrangement of the atoms within the molecule and how tightly they are joined together.

When atoms join other atoms to form molecules, the chemical and physical properties of the compounds are different from those of the elements from which they were formed. These include such things as color, hardness, conductivity, state (solid, liquid, gas), etc. When letters are used to form new words, such as dog, God and good from the letters g, o and d, the meanings of the new words cannot be discovered by observing or studying either the letters g, o and d, or the other words. The new words formed have new and different meanings. This is also true when new molecules form. The properties of the new substances cannot be found by studying the properties of the elements from which they formed or the properties of other similar molecules.
