I don't think so - I don't think any convection is involved. I think boiling uses all three though - heat is conducted, this radiates out and heats the water which when heated starts a convection current.
Radiation is best
conduction and convection..

Conduction
conduction by itself is slower to heat but conduction and convection is faster to heat
Convection has a cycle of what happens. Conduction dosent have a cycle
Conduction :)
Barbecuing, depending on what specific process it is referring to, could be either radiation, convection, or conduction. Radiation is when energy is released in the form of a photon, so the flames of the barbecue (light energy) are a form of radiation. Conduction is when energy is transferred through contact, or collision, therefore, the things you are cooking on the barbecue, are being heated through conduction with the metal. Convection is when energy travels through energy-containing particles (other than photons), so the steam rising from the coals is convection currents.
Lack of a flow medium will inhibit conduction and convection.
