Explain the three states of matter on the basis of characteristics of particles/ molecules of matter.​
Xelga [282]

Answer :

<em><u>Explanation For The Three States OF Matter On the Basis OF Characteristics Of Particles / Molecules OF Matter.</u></em>

<h3><em><u>S</u></em><em><u>o</u></em><em><u>l</u></em><em><u>i</u></em><em><u>d</u></em><em><u>:</u></em><em><u> </u></em></h3>

<em><u>In solids the molecules are closely packed . There is a strong force of attraction between the molecules and the space between them is very small (almost negligible). The molecules are , therefore, not free to move . They merely vibrate their mean positions . This makes solids hard and difficult to compress , giving them a fixed shape and size.</u></em>

<h3><em><u>L</u></em><em><u>i</u></em><em><u>q</u></em><em><u>u</u></em><em><u>i</u></em><em><u>d</u></em><em><u> </u></em><em><u>:</u></em><em><u> </u></em></h3>

<em><u>In the case of liquids , the molecules are not closely packed. They do not attract each other as strongly as the molecules of solids. Thus, the intermolecular spaces are larger and the molecules are able to move about more freely . This makes liquid flow and take the shape of the container into which it is poured. Thus, liquids have a fixed volume but no def</u></em><em><u>i</u></em><em><u>nite shape of their own .</u></em>

<h3><em><u>G</u></em><em><u>a</u></em><em><u>s</u></em><em><u> </u></em><em><u>:</u></em><em><u> </u></em></h3>

<em><u>In the case of gases, the molecules hardly attract each other. They lie far a part from each other and the intermolecular spaces are, therefore, very large. . The intermolecular force of attraction is so weak that the molecules have great freedom of movement . As a result , gases have neither a fixed shapenor a fixed volume . They completely full up spacw available to them. They can be easily compressed as well, thus decreasing the gaps between their molecules .</u></em>

Yuri [45]
I think the correct answer from the choices listed above is option A. A can of diet soda will float in water while a can of regular sugar soda will sink. This is due to the reason that the regular soda is more dense than the diet soda. Hope this answers the question.
