science-heating and cooling
What is conduction?
Transfer of thermal energy by the vibration of particles
What is convection?
Transfer of thermal energy when particles in a heated fluid rise
What is a convection current?
The movement of heated fluids where hot fluid move upwards, and cold fluid moves downwards
What is infrared radiation?
Radiation given off by the Sun and other objects that brings about energy transfer
What is radiation?
The transfed of energy as a wave
What is temperature?
A measure of the motion and energy of the particles
What is a thermal conductor?
Material that allows heat to move quickly through it
What is a thermal energy store?
A store containing energy due to the vibration or movement of particles of a substance
what is a thermal imaging camrea?
A camrea that absorbs infrared and produces a (false colour) image
What is a thermal insulator?
Material that only allows heat to travel slowly through it
What is a thermometer?
Instrument used to measure temperature
