Right from an adrenaline rush to brewing a base in a test tube… it is there in our own biological system and also in the external environment. The properties which are independent of the quantity of the substance present in the system e.g. The law states that notwithstanding the number of steps or stages in a reaction, the total change of enthalpy for a particular reaction amounts to an aggregate of all changes. If  q is the amount of heat absorbed by the system and  w is the work done on the system, the change in internal energy, If volume remains constant, no work is done then, Note :- q and w are not state functions but the sum of the two (q + w) which represents  is a state function. Heat of neutralization of every strong acid by a strong base is identical. Exemplar Questions Class 11 is a very important resource for students preparing for the Examination.
