(a) shape
(b) volume
(c) compressibility
(d) diffusion
(e) fluidity
CBSE Class IX Science LA (5 Marks)
Answers
Answer:
( a ) Shape
Solid :
They have a definite shape
Liquid
They do not have a definite shape. They acquire the shape of container in which they are poured
Gas
They do not have a definite shape
( b ) Volume
Solid :
They have a definite volume.
Liquid:
They have a definite volume
Gases:
They do not have definite volume.
( c ) Compressibility
Solids :
They are completely non compressible.
Liquids:
They are slightly compressible.
Gases:
They are highly compressible.
( d) Diffusion
Solid :
They normally do not show the property of diffusion. They can diffuse in liquid.
Liquid:
They show the property of diffusion. As a result, solids, liquids and gases all can diffuse into liquids.
Gases:
They diffuse very rapidly.
( e ) Rigidity/Fluidity
Solids:
They possess rigidity, therefore there is no fluidity.
Liquids:
Liquids can flow, therefore they possess fluidity which is lower than that of Gases
Gases:
Gases flow more easily than liquids and thus have the highest fluidity.
