What is the relationship between air temperature and air density?
Answers
Answer:
As pressure increases, with temperature constant, density increases. Conversely when temperature increases, with pressure constant, density decreases. Air density will decrease by about 1% for a decrease of 10 hPa in pressure or 3 °C increase in temperature.
Answer:
Although it may seem like it sometimes, weather forecasters don't just make up their predictions. They use the best available science, as well as three key variables that are critical to understanding weather: air pressure, temperature and air density. These variables are essential because, like a well-organized set of drill sergeants, they control how air behaves, and thus, they control the weather. However, they are not mutually exclusive. Like a set of siblings, each variable is closely related to the others (whether they like it or not!).
Explanation:
Pressure and temperature are related to each other by Gay-Lussac's Law. This law says that P1T1=P2T2, or the initial pressure multiplied by the initial temperature is equal to the product of the final temperature and the final pressure. Pressure and temperature have an inverse relationship. In other words, increasing one, will cause the other to decrease.
So if you increase the air temperature, the pressure is going to decrease. If you decrease the air temperature the pressure is going to increase
