The mass per unit volume of a substance is called density. (density = mass/volume). Arrange the following in order of increasing density – air, exhaust from chimneys, honey, water, chalk, cotton and iron.
(a) Tabulate the differences in the characterisitcs of states of matter.
(b) Comment upon the following: rigidity, compressibility, fluidity, filling a gas container, shape, kinetic energy and density.

Explanation:
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
Rigidity: The condition which do not alters the shape of solids.
Compressibility: Compressing particles of gases
is called compressiblity.
Filling a gas container: In the laboratory, after the preparation of gases, they are collected in gas jar. This is called filling a gas container.
Fludity: Fluidity means flowing of liquids freely.
Shape: Things are in which form is called shape.
Kinetic energy: The energy possessed by moving body is called kinestic energy.
Density: Density is the mass per unit.
