Question

which method of heat transfer can occur in empty space? choose one option a radiation b convection c conduction d all of the above

Explanation:

• Conduction requires direct contact between particles (e.g., heat transfer through a solid), so it can't occur in empty space.
• Convection involves the movement of fluid (liquid or gas) particles, and empty space has no fluid, so convection is not possible.
• Radiation is heat transfer via electromagnetic waves (like light or infrared). Electromagnetic waves can travel through a vacuum (empty space), as seen with the Sun's heat reaching Earth through space. So only radiation can occur in empty space.

Answer:

A. Radiation
