convection
Convection currents are the vertical circular movements of fluids that transfer due to changes in density.
The density of fluids decreases as temperature increases. This is because heat makes the particles in fluids move faster and spread farther apart, which means that there are fewer particles in a given volume.
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.
The process of heat transfer in liquids is convection.

Wrong, transfer of heat does take place in fluids. In fact it can take place more efficiently in fluids than in solids because convection is possible in fluids.

Wrong, transfer of heat by conduction does take place in fluids.
Pump relay is used to increase the pressure of incompressible fluids (i.e., density is constant for change in pressure) Compressor relay is used to compress the pressure of compressible fluids (i.e.,density varies with pressure)

Yes
They transfer, fluids, gases and vacuum signals.
