Which two kinds of energy are primarily associated with flames?

• A. Thermal energy and radiant energy
• B. Nuclear energy and sound energy
• C. Kinetic energy and chemical energy
• D. Potential energy and electrical energy

Answer: (A)

Verified step by step guidance

1. Understand that flames are the visible, hot part of a combustion reaction where chemical energy is converted into other forms of energy.
2. Recognize that thermal energy (heat) is a major form of energy released in flames, as the combustion process produces high temperatures.
3. Identify that radiant energy (light) is also emitted by flames, which is why flames are visible and can produce light.
4. Note that nuclear energy, sound energy, kinetic energy, potential energy, and electrical energy are not the primary forms of energy associated with flames in typical combustion.
5. Conclude that the two primary kinds of energy associated with flames are thermal energy and radiant energy.
