It is related by the grams that are measured by density
In convection less molecules occupy large volume as in air to reduce the density.
Convection is the movement of matter due to differences in density.
No Density also drives convection.
Differences in a materials __________ is what drives convection
Density
density
convection
no convection is heat contacted with liquid
A convection cell is a system in which a fluid is warmed, loses density and is forced into a region of greater density. The cycle repeats and a pattern of motion forms. Convection cells in Earth's atmosphere are responsible for the blowing of wind, and can be found in a variety of other natural and manmade phenomena. Matter is constantly losing density in convection cells.
Density plays a crucial role in convection because it determines the buoyancy of a material. In convection, warmer, less dense material rises while cooler, denser material sinks. This movement of material creates the circulation patterns characteristic of convection.
Convection
Hot air has less density and will therefore move upwards.
