1Heat is transferred in three different ways. These are by radiation, convection and conduction.
- ATrue
- BFalse
2[blank_start]All[blank_end] objects are continually emitting (from the [blank_start]surface[blank_end] of an object) and [blank_start]absorbing[blank_end] infrared radiation. An object that't hotter than its surroundings emits [blank_start]more[blank_end] radiation than it absorbs (cooling down). An object that's cooler than its surroundings emits [blank_start]less[blank_end] radiation than it absorbs (warming up). The [blank_start]hotter[blank_end] an object, the more infrared radiation it emits in a given time. [blank_start]Dark, matte[blank_end] surfaces absorb infrared radiation, while [blank_start]light, shiny[blank_end] surfaces reflect radiation.
