4Where does conduction usually occur?
- AIn solids
- BIn liquids
- CIn gases
5Conduction is the process where by [blank_start]vibrating particles[blank_end] pass on extra [blank_start]kinetic energy[blank_end] onto neighbouring [blank_start]particles[blank_end]
- Avibrating particles
- Bkinetic energy
- Cparticles
6Why are metals good conductors?
- AThey have ions that are free to move
- BThey thev a shiney surface
- CThe are strong
7Where does convection occur?
- AIn solids
- BIn Liquids
- CIn gases
8Convection occurs when [blank_start]energetic[blank_end] particles move from the [blank_start]hotter[blank_end] region to the [blank_start]cooler[blank_end] region bringing the [blank_start]heat energy[blank_end] with them
- Aenergetic
- Bhotter
- Ccooler
- Dheat energy

12An object that is cooler than its surroundings [blank_start]absorbs[blank_end] more energy than it [blank_start]emits[blank_end]
- Aemits
- Babsorbs
13What objects absorb and emit infrared radiation the best?
- AShiny
- BDark
- CLight
- DMatt
14The rate of evaporation would be faster if....
- AThe temperature was higher
