This Article is about frequently used basic physics equations. I have covered most of physics equations for class 11 and 12. Earlier I had made a physics formula diary which has been available for free download. Now this Physics formulas and concepts pdf is little bit detailed in nature and there are the times when you study […]
1)The mean energy transferred between the two system as a result of pure thermal interaction is called Heat.It is the transfer of energy from the higher temperature object to a lower temperature object.
2) The total amount of energy transferred as heat is conventionally written as Q for algebraic purposes. Heat released by a system into its surroundings is by convention a negative quantity (Q < 0); when a system absorbs heat from its surroundings, it is positive (Q > 0).
3) Heat is similar to work as both represent ways of transferring the energy.
Many times i have had users ask me a question which book to opt between H.C Verma Concepts of physics and NCERT physics books. My answer is you can keep both the books set for your preparation as NCERT is nice book to learn a good concepts and is according to the exam level of class 11 and class 12.
