- Dark, dull colour feels hotter- better at emitting radiation.
- Heat radiation is energy being transferred in waves (infrared)
- No particles are required for eat transfer by radiation.
- energy from the sun travels through space where there are no particles.
- Surfaces that are dull and dark are good at emitting radiation and absorbing.
- Surfaces that are light and shiny are good at reflecting heat radiation.
- White clothing keeps you cooler.
