The higher the temperature, the lower or higher the air pressure.

The higher the temperature, the lower the air pressure.

According to Baidu Library, the higher the temperature, the lower the pressure. Pressure formula: P=F/S, according to the formula, pressure F belongs to temperature rising, atmosphere thinning and density decreasing; So in this particular thin atmosphere, the pressure drops and the air pressure is relatively low.

The concept of air pressure is the atmospheric pressure acting on a unit area, that is, it is numerically equal to the gravity of a vertical air column extending upward to the upper limit of the atmosphere. The famous experiment in the Madeborg hemisphere proved its existence. The international system unit of air pressure is Pascal, abbreviated as Pa, and the symbol is PA. In meteorology, people usually use kilopascals (kPa) or hectopascals (hpa) as units. Other commonly used units are bar (bar, 1 bar = 100000 Pa) and centimeter mercury column (or centimeter mercury column). Air pressure varies not only with height, but also with temperature. The change of air pressure is closely related to the change of weather.
