Gases have:
Gases have:
The correct option is D No definite volume definite shape and are highly compressible
Definition:
Matter: Anything or everything which occupies space, possesses mass, and offers resistance to any stress applied
on it is called matter.
Specific property determines the physical state of matter.
- The forces of attraction between the particles are strongest in solids, less strong in liquids, and negligible in gases.
- The inter-particle spaces or distances between the particles are minimum in solids, a little more in liquids, and maximum in gases.
- The movement of particles is minimum in solids, more in liquid, and maximum in gases.
The explanation for the correct option:
Options (D):
Gases have no definite volume and shape and are highly compressible. Example: Air, oxygen, carbon dioxide, steam, etc.,
- Gases have neither a fixed shape nor a fixed volume. Hence, they do not have fixed boundaries.
- They can flow in all directions and can be easily compressed.
- In a given space, the number of particles in gases is less than that in solids and liquids.
- The constituent particles of gases have maximum kinetic energy,
because of the presence of large inter-particle spaces between them and therefore, they show a random
motion by moving in all directions.
The explanation for incorrect options
Option (A):
Solids have a definite volume, and definite shape, and are not compressible. Example: Wood, sugar, rocks, minerals, sand, iron, etc.,
Option (B):
Liquid has definite volume but no definite shape and is compressible. Example: Water, milk, petrol, alcohol, etc.
Therefore option (D) is correct.
