Answer: By transforming energy from one type to another.

Explanation:

Energy is not destroyed, it is conserved. During a thermodynamic process, it is transformed from one type to another. The first law expresses a system energy balance. Energy flows in a system (work and heat) are related to changes in system Energy. Thus the first law of thermodynamics says: "The sum of the heat exchanged by a system and the work done by or in a system is equal to the variation of the internal energy of that system."

Instead of the traditional route of upward mobility as a way to achieve assimilation
vampirchik [111]

Answer:

Social mobility is an issue that should be of interest to States, since a country where mobility is fluid leverages its human capital by allowing its citizens to develop their potential, where the primary success factor in a country with a high mobility rate social is personal merit, what is known as meritocracy; The type of system that the whole country craves. If we know that our efforts will be recognized and rewarded, we try harder and with that the states aspire to have enterprising citizens.

Now, in this understanding of ideas, in a country without social mobility the consequences are the opposite. If merit is not rewarded and our economic destiny is predetermined since we were born, why study? Why work? Why work? Hope is lost. A country without social mobility is in danger of generating frustration and resentment, which, in extreme cases, could even cause social instability.

Based on the above, we can define mobility as the possibility that people have to move up or down in the socioeconomic welfare scale. In a country it is important to have opportunities for social mobility to build a more just, integrated and efficient society (ESRU, 2008).

Thus, when we talk about social mobility we refer to the changes that people experience with respect to other individuals in the socioeconomic well-being scale of a country, and in this understanding we understand that it is positive that mobility is positively given in a country. social, since without this the chances of someone improving their economic situation in relation to others, affected by their individual capacity, are so small. That is why we will analyze the types of social mobility that they can present in a society
