The Council for the Indian School Certificate Examinations (CISCE) [1] is a non-governmental privately held national-level [2] [3] board of school education in India that conducts the Indian Certificate of Secondary Education (ICSE) Examination for Class X and the Indian School Certificate (ISC) for Class XII. [4]
The theory exams are conducted for a duration of 3 hours, while the duration for practical exams depends on the subject. CBSE Board conducts the 10th and 12th National Level Examinations. Two times in the Year, Midterm and final term examination, which is conducted in November and February–March. [4]
The macroscopic energy equation for infinitesimal volume used in heat transfer analysis is [6] = +, ˙, where q is heat flux vector, −ρc p (∂T/∂t) is temporal change of internal energy (ρ is density, c p is specific heat capacity at constant pressure, T is temperature and t is time), and ˙ is the energy conversion to and from thermal ...
However, the Term-I examination was criticised by many for having wrong answer keys, tough question papers and wrong or controversial questions, with a question being dropped in Sociology exam of class 12 and a paragraph in the English Language and Literature exam for class 10 by CBSE following which CBSE dropped the experts who set the ...
The transfer of energy between objects that are in physical contact. Thermal conductivity is the property of a material to conduct heat and is evaluated primarily in terms of Fourier's law for heat conduction. Convection The transfer of energy between an object and its environment, due to fluid motion.
[10] [11] In order to avoid an erroneous interpretation of the phenomenon that is always a nonradiative transfer of energy (even when occurring between two fluorescent chromophores), the name "Förster resonance energy transfer" is preferred to "fluorescence resonance energy transfer"; however, the latter enjoys common usage in scientific ...
A heat engine is a system that converts heat to usable energy, particularly mechanical energy, which can then be used to do mechanical work. [1] [2] While originally conceived in the context of mechanical energy, the concept of the heat engine has been applied to various other kinds of energy, particularly electrical, since at least the late 19th century.
Elastic energy is the mechanical potential energy stored in the configuration of a material or physical system as it is subjected to elastic deformation by work performed upon it. Elastic energy occurs when objects are impermanently compressed, stretched or generally deformed in any manner.
