The correct answer is can be reversed with no net change in either system or surroundings
Reversibility is a property that expresses the possibility of making the physical processes run in the opposite direction, infinitely varying the conditions that cause them.
The concept of reversibility has great importance in thermodynamics (in the foundation of its second principle), since it is the only type of processes that use the least amount of energy possible; thus, reversibly, the physical processes give their greatest performance.
In practice, it is not possible to obtain a completely reversible evolution of a process, because for this to happen, it should take place in an infinitesimal way, and, therefore, take an infinite time to complete. However, in order to obtain the highest possible efficiency, motors, machines, etc., are designed in such a way that the processes carried out on them are extremely similar to reversible processes.

Answer:
True
Explanation:
There was a period when the process of urbanization was only attributed to the developed industrialized countries. But nowadays rapid urbanization is steadily taking place in developing countries as well. There has been a notably positive shift in the rate of this occurring among particular countries of South East Asia. The increase in population and their migration to the cities in search of economic prosperity have increased the migration from the nearby rural areas. Some best examples of this trend are actions like Japan, South Korea, India, China, Bhutan, etc.
