The energy transformation process of a welding torch melting metal involves converting chemical energy into thermal energy.
Chemical energy into thermal energy best represents the energy transformation in the process where a welding torch melts metal by burning acetylene fuel in the presence of oxygen. This is an example of an exothermic reaction where the chemical bonds in the fuel are broken, releasing heat energy that melts the metal.
In contrast, kinetic energy into potential energy, kinetic energy into electromagnetic energy, and potential energy into chemical energy do not accurately depict the energy transformation taking place in this scenario.
