What is the term for the vertical circular movements of fluids that transfer energy due to changes in density

Convection currents are vertical circular movements of fluids that transfer energy due to changes in density.

What term describes the transfer of energy between objects that have different average kinetic energies

The transfer of energy between two objects at different average thermal kinetic energies (temperatures) is referred to as heat transfer. It is always called heat transfer, regardless of what kind of energy is being transferred.

How is sound energy produced and transmitted

by vibration of particles and fluids.
