What are some examples of qualitative and quantitative changes in life?

An example of the law of quantitative change and qualitative change in life is frozen three feet, which is also a question of the relationship between quantitative change and qualitative change. When water freezes, its volume increases by about one tenth, that is, its weight is smaller than that of water. Therefore, ice always freezes on the water surface, and as the temperature drops, the ice layer gradually thickens.

However, the speed of ice thickening is very slow because ice is not easy to transfer heat. It is difficult for the water under the ice to continue to freeze because of the protection of the ice. The frozen thickness is related to "negative accumulated temperature". The so-called "negative accumulated temperature" refers to the cumulative sum of the average temperature below zero in winter. The colder the weather, the higher the negative accumulated temperature and the thicker the freezing.

During the Warring States Period, Qi Weiwang and Tian Ji, the minister, raced horses, each with three horses, namely, the upper Marseille, the lower Marseille and the lower Marseille. As a result, Tian Ji lost three wars. Later, Sun Bin, a military strategist, gave Tian Ji an idea that the horse below should be mounted and the horse above should be mounted.

And China and Malaysia dismounted, and the result of the game was one lose and two win, which was a shoo-in. From defeat to victory, it is a qualitative change, but this qualitative change is not achieved by increasing the number of horses, but by different arrangements and combinations of three horses. The same number and quality of troops will lead to different qualitative results of victory and defeat because of different grouping methods.

The same quantity and quality of labor force, due to different organizations and arrangements, will cause qualitative differences in production results; The ongoing political and economic restructuring in China involves changes in the composition of various political and economic factors. The rigid composition and dynamic composition of economic activities will inevitably lead to different economic effects.
