Responses

an investigation of radiation using a current within a fluid
an investigation of radiation using a current within a fluid

an investigation of conduction through movement of particles within a solid
an investigation of conduction through movement of particles within a solid

an investigation of radiation using electromagnetic waves
an investigation of radiation using electromagnetic waves

an investigation of conduction using collisions between particles

Answer 1

The investigation that would best show the transfer of heat energy without any type of matter as a medium is:

**an investigation of radiation using electromagnetic waves.**

This is because radiation does not require a medium to transfer heat; it can occur through the vacuum of space, as seen with heat from the sun reaching the Earth.
