All objects emit infrared radiation 2 of 8 How does infrared radiation depend on the temperature of an object? The hotter an object is, the more infrared radiation it emits in a given time 3 of 8 Which surfaces are the best emitters of infrared radiation? Dark, matt surfaces emit more infrared radiation than light, shiny surfaces 4 of 8 Which surfaces are the best absorbers of infrared radiation? Dark, matt surfaces absorb more infrared radiation than light, shiny surfaces 5 of 8 Which surfaces are the best reflectors of infrared radiation? Light,shiny surfaces reflect more infrared radiation than dark matt surfaces 6 of 8 How are solids, liquids and gases different? Flow, shape, volume and density are the properties used to describe each state of matter 7 of 8 How are the particles in a solid, liquid and a gas arranged? The particles in a solid are held next to each other in fixed positions 8 of 8
