atoms give off heat in the form of electromagnetic waves

electromagnetic waves travel from place to place through a vacuum

List the correct order of conduction.
1. They collide more vigorously with neighbouring particles
2. Particles at the heated end gain kinetic energy and vibrate vigorously.
3. Particles at cooler end vibrate vigorously.
