    WBJEE 2018: States of Matter

    In this article, students will get chapter notes of chapter States of Matter including important concepts, formulae and some previous year solved questions based on the latest syllabus for WBJEE entrance examination 2018. Every year students get 1-2 questions from this chapter in the examination.

    These notes are prepared by Subject Experts of Chemistry after the detailed analysis of the pattern and difficulty level of last few year papers of WBJEE examination.

    These notes contain the crux of the chapter States of Matter. These notes will help students to save their precious time when only few days are left before the examination.

    These notes include all important topics related to States of Matter like Boyle's law, Charles's law, Gay Lussac's law, Avogadro law, ideal gas equation, Dalton's law of partial pressure, compression factor, Vander Waal's equation etc.

    About the Exam:

    West Bengal Joint Entrance Examination (WBJEE) is a state level common entrance test organized by West Bengal Joint Entrance Examinations Board for admission to the Undergraduate Level Engineering and Medical Courses through a common entrance test in the State of West Bengal.

    Question 2:

    A gas can be liquefied at temperature T and pressure P provided

    (A) T = Tc and P < Pc

    (B) T < Tc and P > Pc

    (C) T > Tc and P > Pc

    (D) T > Tc and P < Pc

    Solution 2:

    A gas can be liquefied when T < Tand pressure P > PC

    Hence, the correct option is (B).
