National Testing Agency (NTA) conducts the JEE (joint entrance examination) every year. It is a platform to provide admissions to the aspiring candidates across the country, into the prestigious technical colleges of our country. Candidates must work tirelessly with intensive hard work and focus to obtain success in this examination. The questions asked in chemistry are much simpler and take lesser time as compared to the questions asked in physics or mathematics. A few important chapters and some concepts are highly significant as there is a pattern in which these questions repeat every year. Going through these questions will give you a fair idea about your preparation status and help you to utilize the remaining time before the examination.
Important Question For States Of Matter
What are some of the most important topics in states of matter?
ANS: States of matter does fall under the important topics, which help you in scoring good in JEE. Following are the concepts that should be studied carefully:
- Different states of matter- liquid, gases, solids
- Van Der Waals forces
- Properties of gases and gas laws
- Kinetic Theory of Gases
- Assumptions made for Kinetic Theory of Gases
- Ideal Gas Law and Dalton’s Law of Partial Pressure
- Graham’s law of diffusion and Gas Eudiometry
- Deviation from ideal gas behaviour and Van Der Waal’s Equation
How to Approach a question in states of matter?
Problem: A gas occupies one litre under atmospheric pressure. What will be the volume of the same amount of gas under pressure of 750 mm of Hg at the same temperature?
V1 = 1 litre
P1 = 1 atm =760 mm of Hg
V2 = ?
P2 = 750 mm of Hg
Using P1V1 = P2V2
760 × 1 = 750 × V2
