P1.1 Flashcards
What is infrared radiation?
All objects emit (give out) and absorb (take in) thermal radiation, which is also called infrared radiation.
Infrared radiation is a type of electromagnetic radiation, which involves waves rather than particles.
What surface is the better at absorbing radiation?
Dark matt surfaces are better at absorbing heat energy than light shiny surfaces.
What are light, shiny surfaces good at?
Light, shiny surfaces are also good reflectors of infrared radiation.
What surface is best for emitting heat?
Dark and matt surfaces.
What is the kinetic theory?
The kinetic particle theory explains the properties of the different states of matter.
What are properties of solids?
They have a fixed shape as particles cannot move from place to place. They cannot be compressed or squashed as particles are close together and have no space to move into.
What are properties of liquids?
They flow and take the shape of their container as particles can move around each other. They cannot be compressed or squashed as particles are close together and have no space to move into
What are properties of gases?
They flow and completely fill their container as particles can move quickly in all directions. They can be compressed or squashed as particles are far apart and have space to move into.
What are the particles like in a solid
