Transfer of heat energy through solids, liquids and gases 3 of 8 What will happen if there is a bigger temperature difference? The energy that is transferred by heating, will be emitted faster 4 of 8 Where is infrared radiation emitted from? From the surface of an object 5 of 8 What will happen if the object is hotter than its surroundings? What will happen if the object is cooler than its surroundings? It will emit more radiation than it absorbs. It will absorb more radiation than it emits 6 of 8 What do dark, matt surfaces do? Absorb more infrared radiation and emit more infrared radiation 7 of 8 What do light, shiny surfaces do? They reflect a lot of the infrared radiation. 8 of 8
