What is the energy transfer process called when electromagnetic energy is emitted from an object?

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

Answer: (C)

The process of energy transfer when electromagnetic energy is emitted from an object is known as radiation. This occurs when energy is transferred in the form of electromagnetic waves, which can travel through a vacuum and do not require a medium to propagate. For instance, the warmth felt from sunlight is a prime example of radiation, as the Sun emits energy in the form of electromagnetic radiation that travels through the vacuum of space to reach Earth. This type of energy transfer is distinct from other methods such as convection, which involves the movement of fluids, or conduction, which requires direct contact between materials. Similarly, evaporation refers to the transition of a substance from a liquid to a gas, which involves the absorption of energy and is not directly related to the emission of electromagnetic energy. Understanding these distinctions clarifies why radiation is the correct classification for this specific energy transfer process.
