ENTROPHY IS DIRECTLY PROPORTIONAL TO TEMPERATURE.THEN WHY IS FORMULA (DELTA)S=Q/T WHERE S IS ENTROPHY AND T IS THE TEMPERATURE VALID.
Hey..Its right that when a system absorbs heat , the molecules start moving faster because kinetic energy increases but for the same amount of energy absorbed at low temperature , the disorder is more than at higher temperature.This shows that entropy is inversely proportional to temperature.
SOLUTION
Since entrophy is defined as the degree of disorderness in the universe & it is true that it is dir. prportional to temp.
but mathematically, disorder of the system is measured by the energy absorbed by the system to attend that disorder.
(delta)s=+ve if heat is absorbed and (delta)s =-ve if heat is evolved.If heat is absorbed at low temp., it becomes more
disordered (i.e- entrophy increases) than when the same amt. of heat is added at higher temp.
so, the req. formula is:- (delta)S =Q/T
