What type of heat transfer describes the warmth felt from a hot lamp?

• A. Convection
• B. Conduction
• C. Radiant
• D. Reflection

Answer: (C)

The type of heat transfer that describes the warmth felt from a hot lamp is radiant heat transfer. This is because radiant heat transfer involves the emission of energy in the form of electromagnetic waves, most commonly infrared radiation, which can transfer heat without the need for a physical medium like air or solid materials. When you stand near a hot lamp, the energy emitted by the lamp travels through space and directly warms your skin. This process is not reliant on air movement (as in convection) or direct contact (as in conduction), but rather on the inherent properties of electromagnetic radiation to transfer energy through waves. Therefore, when you feel warmth from a lamp, it's the result of this radiant heat transfer.
