Name the 3 ways heat is transferred from place to place
Conduction, convection, radiation
1 of 13
Dark matt surfaces are better at absorbing heat than light shiny surfaces, true or false?
True
2 of 13
The colder an object is the more infra red radiation it emits, true or false?
False, the hotter an object is the more infra red radiation it emits.
3 of 13
Can radiation pass through the vacuum of space? If so, why?
Yes it can, because it is a type of electromagnetic radiation that involves waves rather than particles.
4 of 13
Are light shiny surfaces good at emitting and absorbing infra red radiation?
No they are poor, black matt surfaces can absorb and emit radiation well.
5 of 13
Explain the arrangement of particles in a solid, liquid and gas.
Solid=close together, regular pattern Liquid=close together random Gas=far apart, random
6 of 13
Explain the movement of particles in a solid, liquid and gas.
Solid=vibrate around a fixed position Liquid=move around each other Gas=Move quickly in any direction
7 of 13
What are poor conductors of heat known as?
Insulators.
8 of 13
As particles are heated, they vibrate more, and spread this heat by passing on their energy, true or false?
True
9 of 13
What is kinetic theory?
The energy that moving objects have.
10 of 13
When do convection currents occur?
hen particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy.
11 of 13
What does evaporation involve?
liquid changing to a gas.
12 of 13
What is condensation?
When a gas cools and condenses into a liquid.
