In this process, the rate of heat loss is proportional to an environment's temperature minus the object's temperature.
Acceleration due to gravity is the only factor that makes density differences non-negligible in this process according to Boussinesq approximation. The Churchill-Bernstein equation calculates its Nusselt numbers. In this process, the rate of heat loss is proportional to an environment's temperature minus the object's temperature. It occurs when the critical value is less than the (*) Rayleigh number and notably takes place inside the mantle and causes namesake currents. For 10 points, name this mechanism by which heat is transferred between fluids in a process contrasted with conduction.
