When acetylene fuel is burning in presence of oxygen, we have chemical process taking place. The torch is used to heat metal to its kindling temperature in oxy-fuel cutting. The steam of gas is then trained on the metal burning it into a metal oxide that flows out of the spout.
So the energy transformation represents this process is <em>Chemical energy into thermal energy </em>
The correct answer for the question that is being presented above is this one: "Chemical energy turns into thermal energy. " <span>A welding torch produces a flame by burning acetylene fuel in the presence of oxygen. This flame is used to melt a metal. </span> Here are the following choices: <span>A. Chemical energy turns into thermal energy. B. Kinetic energy turns into potential energy. C. Thermal energy turns into electromagnetic energy. D. Potential energy turns into chemical energy.</span>
