Energy transfer by heating

  • infared radiation is energy transfer by electromagnetic waves.
  • All objects emit infared radiation but the hotter the object, the faster it emits infared radiation in a given time.
  • Dark matt surfaces emit and absorb infared radiation better than light shiny surfaces.
  • Light shiny surfaces reflect more radiation than dark matt surfaces.
  • Flow, shape, volume and density are the properties used to describe each state of matter
  • the particles in a solid are held next to each other, vibrating in their fixed positions.
  • the particles in a liquid move about at random and are in contact with each other
  • the particles in a gas move more randomly and are farther apart than particles in a solid or liquid.
  • Metals are the best conductors because they have free electrons.
  • Materials such as wool and fibreglass are good insulators.
  • conduction in…
