When heat from a fire travels in waves or rays from one area to another, this transfer is known as what?

• A. Conduction
• B. Convection
• C. Radiation
• D. Convergence

Answer: (C)

The transfer of heat from a fire through waves or rays is known as radiation. This process involves the emission of energy from the surface of the fire in the form of electromagnetic waves. Unlike conduction, which requires direct contact between materials, or convection, which involves the movement of liquids or gases to transfer heat, radiation can occur in a vacuum and does not need a physical medium to travel through. This is why you can feel warmth from the sun even when you are in the cold of space; the sun's energy travels across empty space to reach you. Therefore, understanding radiation in this context is crucial for recognizing how heat can be transmitted efficiently over distances without direct contact.
