Infrared Radiation

Hand/body would feel warmth if near something hot, they all transfer heat through infared radiation

Heat Transfer avaible through conduction,convection,radiation, evaportation, condensation (all of which require particles)

Infrared radiation properites

• Heat
• All objects (emit/give out/absorb)
• Hotter objects> emit more
• Electromagnetic waves (speed of light)
• Differet coloured surfaces emmit differently
• Different cooloured surfaces absorb differently
• can detect with your skin but not your eyes
• can detect with a special camera (thermogram)
• No particles required

Thermograms

Camera which detects infared radiation (red/white = hot, blue/black = cool)

Absorbing

Darker objects absorb and emit heat better than lighter objects and will cool off more quickly

Dull/Matt objects absorb and emit heat better than shiny objects and will get cool/hot slower
