Saturated and Unsaturated Vapour Pressure

Saturated and Unsaturated Vapour Pressure What is a saturated solution? If in a water sugar solution, the amount of dissolved sugar is equal to the maximum amount that a given amount of water can dissolve at a certain temperature, then that solution is called a saturated solution. What is an unsaturated solution? If in a water sugar solution, the amount of dissolved sugar is less than that amount that a given amount of water can dissolve at a certain temperature, then that solution is called a saturated solution. What is saturated vapour? At a certain temperature in an enclosed space, if the amount of vapour present is equal to the maximum vapour capacity of that space, then that vapour is called saturated vapour. What is unsaturated vapour? At a certain temperature in an enclosed space, if the amount of vapour present is less than the maximum vapour capacity of that space, then that vapour is called unsaturated vapour. What is vapour pressure? Vapour enclosed in a container behaves

11.1 Fossil Fuel

The ruins of plant and animals of ancient periods which are found underground are called fossil fuels.

11.2 Hydrocarbons


11.3 Saturated Hydrocarbons: Alkanes


11.4 Unsaturated Hydrocarbons: Alkenes and Alkynes


11.5 Alcohols, Aldehydes and Fatty Acids


11.6 The Uses of Alcohol, Aldehydes and Organic Acids


11.7 Polymers

Polymerization Reaction: The reaction in which innumerable tiny molecules of any substances are attached with each other and form a large molecule is called a polymerization reaction.

Monomer:

Polymer molecule:

Dimer:When two molecules joins each other, it is called a dimer.

Trimer: When three monomers join one another, it is called a trimer.

Types of Polymers

Polymers can be classified in many ways. However, according to their structure, polymers are of two kinds, such as-

i) Addition Polymer and ii) Condensation Polymer.

i) Addition Polymer

The polymer which is formed in a addition polymerization reaction is called an addition polymer.

Addition Polymerization Reaction

The polymerization reaction in which the monomer molecules are directly connected to one another and form a long-chained polymer is called an addition polymerization reaction.

Preparation of polythene

When ethene is heated in the presence of little amount of oxygen at 1000 atmosphere pressure and 200℃ temperature is applied then polythene is produced.
