Hint: The measurement of disorder or randomness is called entropy. This unpredictability might apply to the entire cosmos, a straightforward chemical event, or even something as basic as heat exchange and heat transport. The irregularity or lack of homogeneity of a thermodynamic system is referred to as disorder.

Complete Step by Step Solution:
When entropy is at its greatest, temperature and energy differences are not possible. Due to the fact that everything has already burned out, it is also known as heat death. At maximal entropy, several things can happen, including:
• • Neutrons, protons, and electrons are broken down.

• • The system is currently in an equilibrium state.

• • There will be a completely haphazard movement.

• • More heat will be emitted, ensuring that there are no hot or cold things and that everything is the same temperature.

• Entropy is also present at a higher rate in the presence of an isolated system. As a result, the system becomes more random or disorderly. A closed system that is separated from the outside world has no energy flowing around its perimeter. As a result, the system does not interact with its environment. One must keep in mind that in a system with a high temperature, there is greater entropy, or randomness, than in a system with a low temperature. As a result, the regularity of the increase in entropy decreases.

Additionally, as a reaction takes place, we see that the reactants are broken down into products, which results in an increase in entropy. The order of entropy is as follows: gases have the highest entropy, followed by liquids, and then solids.

Note: Sometimes it helps to visualise something by using an experiment from the real world. Only when a chemical reaction increases entropy will a reaction take place. Consider burning gasoline. We begin with a liquid containing atoms that are fairly orderly grouped in long chains. We produce a lot of heat, water vapour, and carbon dioxide when we burn it. Since both of them are small gaseous molecules, the degree of disorder among their atoms has increased, as has the ambient temperature.
