Explain the relation between atmospheric temperature and atmospheric pressure
Answers
Explanation:
The relationship between atmospheric pressure and temperature is directly proportional to each other. In simple words, increasing temperature causes an increase in the atmospheric pressure and vice-versa
Answer:
Atmospheric Pressure can be defined as an external force that is exerted by the atmospheric column upon a surface due to the gravitational pull of the earth. Atmospheric pressure can be measured using different unit systems such as millimeters of mercury, psi, millibars, kilopascals, and dynes per square centimeter. But mostly, it is commonly measured by using a barometer which consists of a mercury column in a glass tube. We can study the change in atmospheric pressure by the rise or fall of the mercury level with the change in the weight of the atmosphere.
Both atmospheric pressure and winds play a significant role in controlling the Earth's weather and climate and are known as the controlling factors of Earth. Although the atmospheric pressure and winds are different in terms of physical characteristics but are closely associated with each other.
Here, we have provided a detailed explanation of the pressure and wind system as well as the pressure system of the world which can be taken as a reference by the students for any exam preparation. Also, this article will help them understand the relationship between atmospheric pressure and temperature.
Relation Between Atmospheric Pressure and Temperature
The relationship between atmospheric pressure and temperature is directly proportional to each other. In simple words, increasing temperature causes an increase in the atmospheric pressure and vice-versa.
According to Gay-Lussac's Law, the product of initial pressure (P1) and initial temperature (T1) of a system is equal to the product of its final temperature (T2) and final pressure (P2).
Mathematically, it is written as P1T1=P2T2
To understand the relationship better, we can take the example of car tires. During summertime, the increase in the temperature causes the air molecules to move and use up more individual space, resulting in an increase in atmospheric pressure. Whereas, during winter, the air molecules move slowly and are less active, thus using up little space. As a result, the atmospheric pressure decreases.
