Is atmospheric pressure at sea level constant 1013?
It isn't constant anywhere, no. 1013.25 mb is simply the average pressure, which is particularly important at sea level because that is how observations are standardized. But atmospheric pressure always varies no matter where you are, as a consequence of having weather.
Is atmospheric pressure goes on a downward direction only?
No, atmospheric pressure can fluctuate both upwards and downwards due to various factors such as weather patterns, altitude changes, and temperature variations. However, in general, atmospheric pressure tends to decrease with increasing altitude.
What atmospheric factors affect how a barometer works?
A Barometer primarily measures atmospheric pressure, although atmospheric pressure is affected by air temperature. http://www.answers.com/topic/barometer http://www.answers.com/topic/atmospheric-pressure?method=26&initiator=WANS
Name the 4 main atmospheric factors that influence weather?
The four main atmospheric factors that influence weather are temperature, humidity, air pressure, and wind. These factors interact to determine the type of weather experienced in a particular region.
What are two factors that cause atmospheric pressure to change?
Two key factors that cause atmospheric pressure to change are altitude and temperature. As altitude increases, atmospheric pressure decreases because there is less air above exerting force. Additionally, temperature affects pressure; warmer air expands and becomes less dense, leading to lower pressure, while cooler air contracts and increases density, resulting in higher pressure. These variations contribute to weather patterns and atmospheric dynamics.
What factor besides the temperature affects the boiling point of water?
Air pressure also affects the boiling point of water. The higher the air pressure, the higher the boiling point.
What are the factors for holding the lungs to the thorax wall?
Surface tension from pleural fluid, positive pressure, and atmospheric pressure on the thorax.
Can mean effective pressure less than atmospheric pressure?
no Because any body subject is affected by the atmospheric pressure in the case of its occurrence under the pressure of what it means that the pressure for increased atmospheric pressure.
What is atmosperic pressure of Chicago?
The average atmospheric pressure in Chicago is typically around 1013 millibars, or 29.92 inches of mercury. However, atmospheric pressure can fluctuate due to weather systems and other factors.
What is the general pressure at 30 degrees?
At 30 degrees Celsius (approximately 86 degrees Fahrenheit), the general atmospheric pressure at sea level is about 101.3 kPa (kilopascals) or 1 atmosphere (atm). However, this can vary based on local weather conditions and altitude. It's important to note that temperature itself does not directly dictate atmospheric pressure, as pressure is influenced by factors such as weather systems and geographical location.
What is the most important element of weather?
Temperature is often considered the most important element of weather as it influences many other weather factors such as cloud formation, precipitation, and atmospheric pressure. Temperature also has significant impacts on human comfort, agriculture, and ecosystems.
Why does water boil at 121 degrees?
Water boils at 121 degrees Celsius under normal atmospheric pressure, which is approximately 1 atmosphere or 101.3 kilopascals (kPa). However, it's important to note that this boiling point is specific to conditions at sea level and can vary based on factors such as altitude and atmospheric pressure.
