The maximum work obtainable from a system is given by this energy. it is suddenly compressed to a volume of 1 litre. More the disorder or randomness, the more is entropy.Heat added to a system increases randomness and hence the entropy. compression work or work done on the system. : During each stage of process, the temperature remains constant. Download the free PDF of JEE Main Thermodynamics Important Questions Physics from the link given below. NEET Chemistry is the scoring paper in the medical entrance examination. In National Eligibility cum Entrance Test (NEET), physics plays a crucial role as this paper carries 180 marks. Reason:  Adiabatic expansion of the gas causes lowering of temperature and condensation of water vapours. Total energy of universe is conserved (fixed, constant). In polyatomic molecules the bond dissociation energy is not the same for successive bonds though the bonds are of the same type. Calculating standard enthalpy of reactions, = [ Total energy required for breaking the bonds]  – [Energy given out in forming the bonds], Calculation of bond energy of some specific bond in the molecule. It takes 100 calories of heat from source and leaves 80 calories of heat to sink. :  After undergoing a number of changes, the system returns to its original state.
