    1 :
    2 : Definition It is a sequence of events. It conveys the reader how a change takes place through a series of stages.
    3 : A "process description" is defined as a general description of how a process happens, step by step.   It does not tell the reader what to do; rather, It describes how something happens.
    4 : Examples of process descriptions are any kind of manual, pamphlet, or sheet describing how a type of machine works, how a human process works, or how a type of event works.
    5 : Process descriptions avoid giving commands, avoid using the pronoun "you," and make use of the present tense. Examples: "First, the driver inserts the key in the lock" and Avoid giving commands like: ‘Insert the key in the lock’ PROCESS OF SOLAR ENERGY
    6 : Difference between Instructions and Process Description Instructions Does not simply describe general events Gives commands to readers Tells the reader to do something, step by step Example: Insert the key in the lock. Process Description Simply describes general events Avoids giving commands Tells the reader how a change takes place Example: 1. First, the driver inserts the key in the lock"
    7 : STYLE, TONE and WRITER'S ROLE STYLE: should be Professional TONE: should be efficient, interested, reasoned, fair logic. WRITER’S ROLE: should sound business like and positive and present potential or real problems constructively, discussing how they will be fixed.  
    8 : Present the process description with the clear intent To inform: fully, realistically, and 3. logically
    9 : Uses of Connectives and Keywords
    10 : Example 1 Describe the process of making Rayon represented in the flow chart:
    11 : Cellulose Shredded wood pulp Dissolved Solution of Sodium Hydroxide(Caustic Soda) Setting bath of dil. Sulphuric Acid Spinneret Threads are drawn Wound on reel Washed Dried on roller Wound on bobbin
    12 : Answer The given flow chart 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 acid. After this, the mixture is passed into the spinneret where threads are drawn. This thread is wound on a reel and is washed and dried on a roller. The dried thread is wound on a bobbin and is sent for distribution. Thus, rayon is prepared from cellulose.
    13 : Example 2 Study the flow chart which describes the process of making rice husk cement and write a paragraph describing the process
    14 : Equal weights Lime sludge Rice husk Mixed thoroughly Waste lime in sugar and other industries Cakes prepared Dried in sunlight Burnt in the open Rice husk cement Ground to fine powder Ash collected
    15 : Answer Rice husk and lime 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 mixed with lime. Now it has acquired the properties of cement. Thus the Rice husk cement is produced..
    16 : Example 3 Describe the process of purification of water in a paragraph
    17 : Answer The purification of water is basically a two-step 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 and gravel which remove other impurities and chemicals in it. During or after filtration, antibiotic chemicals are ordinarily added to water to kill any remaining harmful bacteria. Chlorine is one of the most common chemicals used for this purpose. In certain places other beneficial chemicals are also added to water. The resultant water is pure.
    18 : Example 4 Describe the process of purification of water in a flow chart
    19 : Answer Reservoirs Add lime and Aluminium sulphates Aluminium hydroxide settles at the bottom Water filtered through beds of sands and gravel Antibiotics like Chlorine are added to kill bacteria Pure Water
    20 : Prepare a flow chart to describe the process of classification of Education. Example 5
    21 : Answer Education School Education Collegiate Education Higher Education Elementary Education Arts Science Education Education to Polytechnic Special Institutions Secondary Higher Secondary Education Professional Education Medical Paramedical College Agricultural Veterinary Science Colleges Law Colleges Engineering Colleges
    22 : Example 6 Describe the process of classification of Education in a paragraph.
    23 : Answer Education is broadly classified 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. Further, professional education comprises the medical colleges and paramedical colleges, agricultural and veterinary science colleges, law colleges and engineering colleges.
