Notes On Gaseous State This page provides you all details about the gaseous state of BSc standard. Concerned problems will be solved at the end of each concept. Continue till the end to find the easiest explanation of every concept you need in this regard . Postulates of Kinetic Theory of Gases: 1. All gas consist of a very large number of minute particles, called molecules. 2. The gas molecules are extremely small in size and are separated by large distance. The actual volume of the gas molecules is thus negligible as compared to the total volume occupied by the gas. 3. The pressure exerted by the gas is due to the bombardment of the molecules on the walls of the vessel. 4. The gas molecules collide with one another and also with the walls of the vessels. These collisions are perfectly elastic and there is no loss of energy during these collisions. 5. The distance between the gas molecules are very large. Thus, there is no effective force of attraction or r
How to prepare for IIT JAM Chemistry
Follow the the following rules to make your exam smooth and successful.
1. Analyse your IITJAM Chemistry Syllabus Smartly: Read your syllabus bit by bit and
proceed to prepare as follows:
1a. Take the statistics of previous year question papers: Find which types of questions are asked frequently. Which chapters are more important. Find chapter-wise previous year question papers and answers here
2. Find your strength and weakness: Get
a clear map of the chapters you are strong and in which your are weak. Focus
strongly in studying chapters and try to be able to attend all kind of
questions in those chapters. Simultaneously read carefully to make your
concepts strong in weak chapters and skip the weakest chapters. Learn to stay focused during long exams. Also learn time management
3. Practice all kind of questions: MCQ
(Multiple choice questions), MSQ (Multiple select questions), Numerical answer
type questions etc. should be sufficiently practised.
On the examination day, reach the exam centre
before an hour of the scheduled time.
What to do in the examination hall?
1. Read carefully: Always read the
instructions given on the front page carefully and also read and understand the
directions given to attempt a question. This way you can avoid any mistakes due
to overconfidence.
2. Solve the easy question first: Easy
questions in general saves a lot of time. So go for them first, and then try
the next level.
3. Sometimes striking off the wrong options
can give you the right options: Don't always search the right answer. When
you strike off all the wrong options with surety then you get the rest as the
right answer(s). This practice also helps you to avoid answering the first
right option whereas the right option should be all of the above.
4. Don't waste excessive time on one
question: If in any case you are unable to answer any question, dont
give much time to that instead try next question.
5. Try to attempt the leftover
questions: If you get time, try the unattempted questions if any from the
begining.
6. Keep a time check: Save time to check
or revise your answers at the end.
7. Use Scribble pad: Use it for your
rough work and noting down any points to answer a question.
8. Use virtual numerical keypad: In
answering numerical answer type question, use virtual numerical keypad.
