Question

Lindsay is boiling macaroni noodles in a pot of water. The noodles rise and fall as the thermal energy currents move from areas of higher energy to areas of lower energy. Which process is primarily responsible for making the macaroni noodles move in the boiling water?

Answer 1

The process primarily responsible for noodle motion, especially in this scenario, is convection.

In any fluid undergoing uneven heating or cooling, a circulation pattern develops where warmer portions of the fluid rise and cooler portions sink.
