Physical chemistry is the study of macroscopic and microscopic phenomena in chemical systems in terms of the principles, practices, and concepts of physics such as motion, energy, force, time, thermodynamics, quantum chemistry, statistical mechanics, analytical dynamics and chemical equilibria.
Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
Section one consists of 60 MCQs of 1 marks each and Section two consists of the remaining 20 MCQs of 2 marks each. Negative marking is applicable. 30% of the total marks of a question will be deducted for every incorrect answer. [3] In 2006, the WBJEE contained only objective-type MCQ (Multiple Choice Question) type questions.
A multiple choice question, with days of the week as potential answers. Multiple choice (MC), [1] objective response or MCQ(for multiple choice question) is a form of an objective assessment in which respondents are asked to select only the correct answer from the choices offered as a list.
[10] [11] The second quadrant is an e-content which could include e-books, illustrations, Case studies, Open source content, reference links, further reading sources, etc. [12] The third quadrant is about clearing students' queries where students can interact with each other and faculty; any student or faculty can answer a student’s question ...
This is a list of unsolved problems in chemistry. Problems in chemistry are considered unsolved when an expert in the field considers it unsolved or when several experts in the field disagree about a solution to a problem.
This temperature determines the relative solubility of surfactant in an aqueous solution. This is the minimum temperature the solution must be at to allow the surfactant to precipitate into aggregates. [8] Below this temperature no level of solubility will be sufficient to precipitate aggregates due to minimal movement of particles in solution. [8]
The protoscience of chemistry, and alchemy, was unsuccessful in explaining the nature of matter and its transformations. However, by performing experiments and recording the results, alchemists set the stage for modern chemistry. The history of chemistry is intertwined with the history of thermodynamics, especially through the work of Willard ...
