LONG ANSWER QUESTION
1. Give differences between: (a) solids and liquids, (b) liquids and gases on the basis of (i) rigidity
(ii) density (iii) kinetic energy​

Answer 1

$\huge\sf{A᭄nswer:-}$

$\tt\blue{a.}$$\sf\pink{Solid\: :-}$In the solid state, the individual particles of a substance are in fixed positions with respect to each other because there is not enough thermal energy to overcome the intermolecular interactions between the particles. As a result, solids have a definite shape and volume. Most solids are hard, but some (like waxes) are relatively soft. Many solids composed of ions can also be quite brittle.

$\sf\pink{Liquid\: :-}$If the particles of a substance have enough energy to partially overcome intermolecular interactions, then the particles can move about each other while remaining in contact. This describes the liquid state. In a liquid, the particles are still in close contact, so liquids have a definite volume. However, because the particles can move about each other rather freely, a liquid has no definite shape and takes a shape dictated by its container.

$\tt\blue{b.}$Liquids, on the other hand, are less $\sf\red{rigid }$and flow easily.

Answer 2

Solid:− In the solid state, the individual particles of a substance are in fixed positions with respect to each other because there is not enough thermal energy to overcome the intermolecular interactions between the particles. As a result, solids have a definite shape and volume. Most solids are hard, but some (like waxes) are relatively soft. Many solids composed of ions can also be quite brittle.

Liquid - If the particles of a substance have enough energy to partially overcome intermolecular interactions, then the particles can move about each other while remaining in contact. This describes the liquid state. In a liquid, the particles are still in close contact, so liquids have a definite volume. However, because the particles can move about each other rather freely, a liquid has no definite shape and takes a shape dictated by its container.
