Question

Which of the following are associated with gaseous state -
A. Fixed shape, incompressible, and packed closely .
B. Incompressible, fixed shape and size
C. Definite shape, compressible, and fixed volume
D. Highly compressible, no fixed shape and size .

Answer 1

We know that gas is one of the four fundamental states of matter , in which the others are solid, liquid, and plasma . A pure gas may be made up of individual atoms, and elemental molecules may be made from one type of atom, or compound molecules which are made from a variety of atoms .

Complete step by step answer:
The properties of the gaseous state are as follows -
1.They are highly compressible
2.Have very low density
3.They have no defined shape
5.4.The molecules in gaseous state scatter by forces in all directions.
6.The container’s volume is the gas volume.
7.They mix evenly throughout, the elements are very susceptible to reactions and mixtures .
Also gaseous elements have negligible intermolecular forces .
Therefore , as we can see, for our question, the correct answer is ,

So, the correct answer is Option D.

Note: It should be kept noticed how particles differ like :
A . Gases are well separated with no regular arrangement in them.
B . Whilst the liquids are close together with no regular arrangement.
C . In solids, the molecules are tightly packed, usually in a regular pattern.
About their vibration matter, the particles in a:
A . The gases vibrate and move freely at high speeds.
B . in liquids, they vibrate, move about, and slide past each other.
C . but in solids, they do vibrate but generally do not move from place to another.
One, while solving these types of questions , always keep in mind the properties of the fundamental states i.e. gaseous , liquidity and solidification and also about the functionality of their behaviour .
