(Originais Teachy 2024) - Question Hard of Sciences

Consider the following excerpt from a scientific article: 'Energy is constantly transformed from one form to another in natural processes and in technologies that support modern society. In a thermal power plant, the energy contained in the fuel is initially thermal, but through a series of conversions, including mechanical and electrical, it is finally transformed into electrical energy that can be distributed and used to power different devices.' Based on this context, answer: (1) Explain, step by step, the energy transformations that occur in a thermal power plant, from the energy contained in the fuel to the production of electricity. (2) Consider a hypothetical scenario in which the energy conversion efficiency in a thermal power plant is only 20%. If a fuel contains 1 megajoule (MJ) of energy, how much of that energy will be effectively converted into electricity.
