A toy boat is floating in a large metal bucket if you build a fire under the bucket how will most of the heat be transferred from the fire to the boat?

Most of the heat will be transferred from the fire to the toy boat primarily through conduction and convection. The heat from the fire heats the metal bucket, causing it to transfer heat to the water inside through conduction. As the water heats up, it circulates, transferring heat to the toy boat through convection.
