Which is the best example of increasing entropy? a pile of library books is placed in a neat stack on a shelf. a cyclist pedals harder while riding uphill. a deserted field becomes overgrown with weeds. a dining room is cleaned to remove dust.

 A deserted field becomes overgrown with weeds

Explanation: Entropy is the measure of randomness or disorder of a system.

If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to increase and vice versa.

Energy must be used to increase the entropy of the system and thus a deserted field becomes overgrown with weeds , it uses energy and thus the randomness or entropy also increases.

A pile of library books is placed in a neat stack on a shelf has least disorder or  least entropy.

A cyclist pedals harder while riding uphill and thus energy is supplied and the entropy decreases.

A deserted field becomes overgrown with weeds and thus the entropy of the field increases.

A dining room is cleaned to remove dust and thus the disorder is decreasing.

this allows people to make the best decision or pursue the best option. when alternatives are weighed using their advantages and disadvantages, the option whose disadvantages outweigh the advantages (based on a qualitative or quantitative analysis) are shunned while those whose advantages outweigh their disadvantages are pursued.
