High temperature and low pressure

Does the questioner want to ask "the reason for high temperature and low pressure?" The reasons are weather, altitude, and barometer failure.

1. Weather reasons: In hot weather, the temperature will increase and the air density will decrease, resulting in a decrease in air pressure. In addition, if the weather is humid, water vapor will occupy a certain volume of air, which will also cause the air pressure to decrease.

2. Altitude: As the altitude increases, the atmospheric pressure will gradually decrease, and the temperature will also decrease. This is because as altitude increases, air pressure gradually decreases, the mean free path of gas molecules increases, and the probability of collision decreases, resulting in a decrease in temperature.

3. Barometer failure: If the vehicle's barometer fails, it may also lead to high temperature and low pressure. In this case, you need to go to a professional car repair station for inspection and repair.
