- 9. Example 1 Describe theprocess of making Rayon represented in the flow chart:
- 10. Cellulose Shredded wood pulp Dissolved Solution ofSodium Hydroxide(Caustic Soda) Threads are drawn Wound on reel Washed Setting bath of dil. Sulphuric Acid Spinneret Dried on roller Wound on bobbin
- 11. Answer The given flowchart describes the process of making rayon from cellulose. First, cellulose is extracted from shredded wood pulp. Then, the cellulose is dissolved in a solution of Sodium hydroxide. Then, the mixture is immersed in a bath of dilute sulphuric acidd. After this, the mixture is passed into the spinneret where threads are drawn. This thread
- 12. Example 2 Study theflow chart which describes the process of making rice husk cement and write a paragraph describing the process
- 13. Equal weights Rice husk Limesludge Waste lime in sugar and other industries Mixed thoroughly Cakes prepared Rice husk cement Dried in sunlight Ground to fine powder Burnt in the open Ash collected
- 14. Answer Rice husk andlime sludge are mixed together in equal quantity. The mixing is done so thoroughly that the ingredients cannot be easily separated. Secondly, the mixed substance is made into cakes and dried sufficiently in sunlight. Next, it is burnt in the open in a furnace and as a result, reactive ash is formed which can be ground to powder. The powder is
- 15. Example 3 Describe theprocess of purification of water in a paragraph
- 16. Answer The purification ofwater is basically a twostep process. As the first step, water is allowed to stand in large reservoirs where most of the mud, clay and silt settle; this is called sedimentation. Often, in water with high mud content, lime and aluminium sulphates are added to water in the setting reservoirs. These chemicals react in water to form aluminium hydroxide, which settles slowly and carries much of the impurities to the bottom of the reservoirs. As the second step, water is filtered through beds of sand
- 17. Example 4 Describe theprocess of purification of water in a flow chart
- 18. Answer Reservoirs Add lime andAluminium sulphates Water filtered through beds of sands and gravel Antibiotics like Chlorine are added to kill bacteria Aluminium hydroxide settles at the bottom Pure Water

- 20. Answer Education School Education Elementary Education Medical & Paramedical College CollegiateEducation Secondary & Higher Secondary Education Arts & Science Education Agricultural & Veterinary Science Colleges Higher Education Education to Polytechnic & Special Institutions Professional Education Law Colleges Engineering Colleges
- 21. Example 6 Describe theprocess of classification of Education in a paragraph.
- 22. Answer Education is broadlyclassified into three categories. They are school education, collegiate education and higher education. This division is based on the level of education. Next, school education is divided into two branches namely elementary education and secondary and higher secondary education. On its part, collegiate education is branched into three parts. They are:Arts and Science education, professional education and education given by polytechnics and special institutions.
