Convection and radiation transfer thermal energy through matter only, and conduction transfers thermal energy through both matter and empty space.
Radiation and conduction transfer thermal energy through matter only, and convection transfers thermal energy through both matter and empty space.
Convection and conduction transfer thermal energy through matter only, and radiation transfers thermal energy through both matter and empty space.
Conduction, convection, and radiation transfer thermal energy through both matter and empty space.

Answer 1

"Convection and conduction transfer thermal energy through matter only, and radiation transfers thermal energy through both matter and empty space."

Explanation: Conduction and convection require matter (particle interactions and fluid movement), while radiation is electromagnetic and can travel through a vacuum as well as through matter.
