Question

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?

Answer 1

Answer

Chemical energy in to thermal energy

Explanation

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 Chemical energy into thermal energy

Answer 2

The correct answer for the question that is being presented above is this one: "Chemical energy turns into thermal energy. " A welding torch produces a flame by burning acetylene fuel in the presence of oxygen. This flame is used to melt a metal.

Here are the following choices:
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.
