What type of heat transfer would boiling water be considered

Convection.

Explanation:

when a pot of water is placed on the stove to boil, conduction heat warms up the pot, which then heats the water molecules inside. As these molecules heat, convection causes them to move away from the interior of the pot as they are replaced by cooler molecules.

Convection.

Explanation:

"The heat passes from the burner into the pot, heating the water at the bottom. Then, this hot water rises and cooler water moves down to replace it, causing a circular motion. Radiator - Puts warm air out at the top and draws in cooler air at the bottom."

fgravity=10x10=100n case 1

fgravity=30x20=600n case 2

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
