Do you admiration why the acclimate changes all the time? Would you like to fly an aeroplane someday? If you answered "yes" to either of these questions, you charge to apprentice how air molecules move!
When we feel abounding air molecules affective in one direction, we say the wind is blowing. When a ample bulk of air moves downward, that is alleged a downdraft. When a ample bulk of air moves upward, it is alleged an updraft. An aeroplane pilot has to consistently acclimatize to both updrafts and downdrafts. Convection is the appellation anecdotic the advancement and bottomward movement of air (or liquids). The basal account of these movements is differences in density. Density is the bulk of bulk in a accustomed bulk of space. Close air sinks, creating downdrafts, while beneath close air rises, creating updrafts.
Normally, it is adamantine to see air moving, but by creating some smoke, you will be able clue the movement of air molecules.
The smoke rises into the top jar while the basal jar gets clearer.
You acclimated the atramentous cardboard to bigger see the smoke. Smoke is composed of gasses with tiny particles abeyant in them. These little particles acquiesce us to see the commonly airy movements of air. The smoke-filled air has a lower body than the algid air. Density, you ability remember, is how abundant bulk (in this case, air molecules) is in a accustomed bulk of space. The air molecules with the smoke were affective about added than the algid air molecules, colliding more, and blame anniversary added added apart. This fabricated the air beneath dense, so it rose to the top (like a cork rises to float in water). The algid temperature in the freezer acquired the air molecules in the added jar to move about less. Therefore, they collided beneath frequently and confused afterpiece together. This algid air was denser than the begrimed air, so it sank to the lower jar (like a penny sinks in water).
