Indicate how air temperature and atmospheric pressure are interrelated.

Temperature and atmospheric pressure are interrelated factors.
So when the air is heated, its volume increases, the air density decreases, and, accordingly, the pressure decreases. When the air is cooled, the opposite occurs. The same relationship is observed with an increase in altitude above sea level. The higher, the more rarefied the air becomes, the atmospheric pressure decreases, and, accordingly, the temperature also decreases. It is reliably known that with an increase in altitude for each kilometer, the air temperature decreases by about 6 degrees.
