Is newt boiling in a hot cauldron convection conduction or radiation?

The process of a newt boiling in a hot cauldron involves primarily conduction. Conduction is the transfer of heat through direct contact between objects of different temperatures. In this case, the heat from the cauldron is directly transferring to the newt through contact, causing it to boil. Convection and radiation may also play minor roles in the overall heat transfer process, but conduction is the primary mechanism at work here.
