convection means transmission of heat in liquid. consider an example that when u have more tension at that time ur temperament become hot it starts flowingn in our red blood corpuscles (water) so it become hard hence dense.
It's the change (decrease) in density with heating that produces the currents that we refer to as convection currents.

this question doesnt make sense
In convection less molecules occupy large volume as in air to reduce the density.
It's the change (decrease) in density with heating that produces the currents that we refer to as convection currents.
Friction creates heat - heat travels by convection, conduction or radiation.
It is related by the grams that are measured by density
Lake freezes first at the surface is convection involved
No Density also drives convection.
Convection is the movement of matter due to differences in density.
