To determine the direction of air movement based on temperatures, we look at the concept of airflow, which tends to move from areas of higher temperature (less dense air) to areas of lower temperature (more dense air). In this case, we have:
- x = 22 (higher temperature)
- y = 18 (lower temperature)
- z = 18 (same as y)
Since air will move from the area with the higher temperature (x) to areas with lower temperatures (y and z), we can complete the statement as follows:
"Air will move from x (22 degrees) to y (18 degrees) and z (18 degrees)."
This indicates that the air will flow from x towards both y and z since they are at the same temperature.
