Question Answer
How can heat energy be transferred? Conduction Convection Radiation
How does heat radiation transfer heat energy? By Infrared Radiation (IR)
How do conduction and convection transfer energy? Through particle movement
In which state of matter is conduction most prominent? Solids
In which state of matter is Convection most prominent? Liquids and Gases
What can emit IR Solids, liquids and gases
The bigger the temperature difference... ... the faster the energy is transferred by heating
State the types of materials that adsorb IR more efficiently. Dark, matt surfaces
What type of materials emit more radiation? Shiny, light surfaces
Why would solar panels be a dark colour? So they absorb more IR making the system much more efficient
