Each subject in the examination is graded out of 100 marks. [3] For subjects like Physics, Chemistry, Biology, Home Science, Mathematics, Geography, etc. for which practical exams are also conducted, 30/20 marks are reserved for practicals and internals and 70/80 marks for the theory exams.
Elizabeth Loftus' and John C. Palmer's car crash experiment shows that leading questions can produce false memories (1974) Benjamin Libet's experiment on free will shows that a readiness potential appears before the notion of doing the task enters conscious experience, sparking debate about the illusory nature of free will yet again. (1983)
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.
The Chemistry, Biology, Physics and Design Technology was last updated for first teaching in September 2014, with syllabus updates (including a decrease in the number of options), a new internal assessment component similar to that of the Group 5 (mathematics) explorations, and "a new concept-based approach" dubbed "the nature of science". A ...
The exam has 60 multiple-choice questions (48 single-correct and 12 multi-correct), with a 2-hour time limit. It's held on the last Sunday of November, and the top 400 students (200 each, group A & group B) advance to the Indian National Physics Olympiad (INPHO). The syllabus aligns broadly with up to CBSE Standard 12 Physics.
Chemical thermodynamics is the study of the interrelation of heat and work with chemical reactions or with physical changes of state within the confines of the laws of thermodynamics. Chemical thermodynamics involves not only laboratory measurements of various thermodynamic properties, but also the application of mathematical methods to the ...
Chemical kinetics, also known as reaction kinetics, is the branch of physical chemistry that is concerned with understanding the rates of chemical reactions. It is different from chemical thermodynamics, which deals with the direction in which a reaction occurs but in itself tells nothing about its rate.
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.
