Question

Question: Give three examples, other than those mentioned in this Chapter, of naturally occurring processes in which order goes to disorder. Discuss the observability of the reverse process.

Short answer

The three examples are as follows:

(i) A pile of compost disintegrating

(ii) The conversion of mechanical energy to heat energy by friction

(iii) The various metal oxidation (zinc, iron, copper, etc.) when exposed to the air

Step-by-step solution

Understanding of entropy 

The entropy of a system is a state variable, and it can be described as the randomness of any system. The universe's entropy is always increasing.

Step 2:Examples of naturally occurring processes in which order goes to disorder

The three examples of naturally occurring processes in which order goes to the disorder are as follows:

(i) A pile of compost disintegrating

(ii) The conversion of mechanical energy to heat energy by friction. A sliding body loses speed and ultimately stops, and the contact surfaces become more heated.

(iii) The various metal oxidation (zinc, iron, copper, etc.) when exposed to the air.

In all the above processes, the reverse of the process is not observed.
