Question

diagram
infrared rays (heat)
heat being absorbed by cooler body
source
this is an example of convection, conduction or radiation?
conduction
convection
radiation

Explanation:

• Conduction is heat transfer through direct contact between materials. Here, there is no direct physical contact between the source and the person.
• Convection involves heat transfer through the movement of fluids (liquids or gases). The diagram shows infrared rays (electromagnetic waves) which are not related to fluid movement.
• Radiation is heat transfer through electromagnetic waves (like infrared rays). The diagram shows infrared rays (heat) being emitted from a source and absorbed by a cooler body (the person), which is characteristic of radiation.

Answer:

radiation
