Explanation:
Entropy -
In a system, the randomness is measured by the term entropy .
Randomness basically refers as a form of energy that can not be used for any work.
The change in entropy is given by amount heat per change in temperature.
<u>entropy increases as the randomness increase , </u>
and ,
<u>entropy decrease as the randomness decreases . </u>
I. A piece of fruit freezes in liquid nitrogen.
randomness decreases , and so entropy decrease .
II. Librarians put library books back onto shelves at the end of the day.
randomness decreases , and so entropy decrease .
III. Liquid nitrogen boils in a beaker at room temperature.
change in state from less random liquid to gas , randomness increases , hence entropy increases
IV. Dry ice sublimes .
change in state from less random solid to gas , randomness increases , hence entropy increases .
V. A balloon collapses as its contents cool in liquid nitrogen .
cooling process , reduces the randomness , hence , entropy decreases .
