Tabulate the differences in the characteristics of states of matter.


Question 2. (a) Tabulate the differences in the characteristics of states of matter.
(b) Comment upon the following:
rigidity, compressibility, fluidity, filling a gas container, shape, kinetic energy and density.
Answer:
 (a)
S.NO
Property
Solid
Liquid
Gases
1.
Shape
They Have definite shape
They do not have definite shape
They do not have definite shape
2.
Volume
They have definite volume
They do not have definite volume
They do not have definite volume
3.
Density
They have high density.
Liquids have less density than solids.
Liquids have least density.
4.
Kinetic energy of particles.
Least
More than solids
Maximum
5.
Compressibility
Negligible
Low
High

Rigidity: It is the property of matter to resist the change of its shape.
Compressibility: It is the property of matter in which its volume is decreased by applying force.
Fluidity: It is the ability of matter to flow.
Filling a gas container: On filling a gas takes the shape of the container.
Shape: Having definite boundaries.
Kinetic energy: It is the energy possessed by the particles of matter due to its motion.
Density: It is the ratio of mass with per unit volume
