Which of the following transformations occurs at a power plant?

The transformation that occurs at a power plant is the conversion of chemical energy to electrical energy. In many power plants, particularly fossil fuel power plants, fuel such as coal, natural gas, or oil undergoes combustion, which releases thermal energy. This thermal energy is then used to heat water, creating steam that drives a turbine. As the turbine spins, it converts the kinetic energy of the steam into mechanical energy, which is then transformed into electrical energy through a generator.

This process illustrates the fundamental principle of energy conversion. In this case, the chemical energy stored in the fuel is utilized to produce electrical energy that can be distributed to homes and businesses. Understanding this transformation is crucial in recognizing how energy production affects our daily lives and contributes to the overall energy grid.
