Want this question answered?
Convection is the movement caused within a fluid by "warm currents". The hotter fluid will rise, pushing the cooler fluid down, which then in turn gets heated, creating a continuous cycle.
Convection is transferred by the larger-scale motion of currents in the fluid.
true
No, it is not true that heat transfer by the movement of currents within a fluid is called density; it is actually called convection. Density is something else entirely, it refers to weight per a given volume. Of course, density is relevant to convection. Heat causes fluids to expand and therefore to become less dense, and therefore to rise.
It is called Convection.

When a fluid (liquid or gas) is heated, it expands. The heated fluid is therefore less dense than the fluid around it, so it rises.Colder fluid then sinks down to replace it and this sets up a movement of fluid called a CONVECTION CURRENT.

convention current is heats by the mass movement of heat particles into an area of cooler fluid.
Convection
If it is a result of temperature differences, it is called convection.
