Question

1. The mass per unit volume of
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.
2. (a) Tabulate the differences in
the characterisitcs of states
of matter.​

Answer 1

Explanation:

1. Air < Exhaust from chimneys < Cotton < Water< Honey < Chalk < Iron.

2.Solid-

• Definite shape and definite volume.
• Force of attraction is maximum between the particles.
• Incompressible.
• Kinetic Energy of particles is minimum.
• Highest density.

Liquid-

• Indefinite shape and definite volume.
• Force of attraction is less between particles than solid.
• Can't compress.
• Kinetic energy of particles is more than solid.
• Density is low than solid.

Gas-

• Neither a definite shape nor a definite volume.
• Negligible force of attraction between the particles.
• Can be compress.
• Kinetic energy is maximum.
• Lowest density.

Hope it help u..

Answer 2

Air, water, exhaust from chimneys, chalk, cotton, honey, iron.
