<u>Answer</u>
Chemical energy in to thermal energy
<u>Explanation</u>
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>
A dependent variable could be oxi clean because it needs water to work.
