Answer the following.
a) Tabulate the differences in the characteristics of matter.
b) Comment upon the following: rigidity, compressibility, fluidity, filling a gas container,
shape, kinetic energy and density.
Answers
(a) .No Property Solid Liquid Gases
1. Shape They have a definite shape They do not have a definite shape They do not have a definite shape
2. Volume They have a definite volume They do not have a definite volume They do not have a definite volume
3. Density They have high-density Liquids have less density than solids Gases have the least density
4. The kinetic energy of particles Least More than solids Maximum
5. Compressibility Negligible Low High
(b)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: Matter can flow.
Filled 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
Answer:
A]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: Matter can flow. ... Kinetic energy: It is the energy possessed by the particles of matter due to its motion
B]1) Rigidity = It is the tendency to maintain the shape whenever outward force is applied.
2) Compressibility = It is the tendency to decrease the volume of the matter by applying force and not changing the mass.
3) Fluidity = It is the tendency of matter to flow.
4) Filling of a gas container = To fill the container completely by gas. Example :- L.P.G, C.N.G. are filed with gas.
5) Shape = Shape of a matter depends on inter-particle force of attraction and inter-particle spaces.
6) Kinetic Energy = It is the energy present in a particle of matter during its motion.
7) Density = It is the mass occupied by a matter per unit volume.
