18. Which investigation would best show the transfer of heat energy without any type of matter as a medium?(1 point)

Answer 1

The investigation that would best show the transfer of heat energy without any type of matter as a medium is demonstrating the process of radiation. Radiation is the transfer of heat energy through electromagnetic waves, such as infrared radiation, which can occur in a vacuum where no matter is present. An example of this could be measuring the temperature of surfaces exposed to sunlight, where heat is transferred from the sun to the Earth through the vacuum of space.
