BRAINTWISTER!

ok guys so a microwave is radation right? i mean its in the name, WAVE.
But i saw this, "Microwaves cook food by heating the liquid water it contains. Each water molecule has a slight positive electric charge on one side and a slight negative charge on the other."
So could you say this is radiation and convection??

Answer:

Convection is the transfer of energy by movement of a medium, whereas radiation is the transfer of energy by, well, thermal radiation. Conduction also requires a medium, but, again, it is a fundamentally different mechanism than either convection or radiation; in this case it is the transfer of energy through a medium

Answer:

Microwave radiation utilizes short, high-frequency waves that penetrate food, which agitates its water molecules to make friction and transfer heat. If you're heating a solid substance, this energy is transferred throughout the food through conduction, while liquids do so through convection.
