a welding torch produces a flame by burning acetylene fuel in the presence of oxygen. this flame is used to melt a metal. which energy transformation represents this process?\no chemical energy into thermal energy\no kinetic energy into potential energy\no kinetic energy into electromagnetic energy\no potential energy into chemical energy
Answer
Brief Explanations:
Acetylene fuel burning is a chemical - reaction. Chemical energy stored in acetylene and oxygen is released as heat (thermal energy) to melt the metal.
Answer:
chemical energy into thermal energy
