What else can I help you with?
The force exerted by the weight of a column of air on a surface is called?
Air Pressure The force exerted by the air above is called?
Is the unit of measure for atmospheric pressure most commonly found on weather maps?
In weather maps, atmospheric pressure is measured in millibars. Standard atmospheric pressure is 1013.2 millibars at sea level. Air pressure varies depending on temperature and air density.
What is the atmospheric pressure if it is 685 Torr?
The atmospheric pressure would be 685 Torr. It is a unit of pressure commonly used in chemistry and is equivalent to approximately 0.905 atm or 25.4 inHg.
What is a high air pressure system known as?
A high air pressure system is commonly known as an anticyclone. It is a region where the atmospheric pressure at the surface is greater than its surrounding areas. Anticyclones are associated with clear skies, dry weather, and stable atmospheric conditions.
What is A device that measures atmospheric pressure is called?
A device that measures atmospheric pressure is called a barometer. It is commonly used in weather forecasting to track changes in air pressure, which can indicate changing weather patterns.
When intrapulmonary pressure is above atmospheric pressure what is able to occur?
When intrapulmonary pressure is above atmospheric pressure, air will move out of the lungs due to the pressure gradient, allowing for expiration. This is known as exhalation.
What unit of measure for atmospheric pressure is most commonly found on weathering maps?
milli bar
What is effective or gauge pressure?
Effective or gauge pressure refers to the pressure measured relative to the ambient atmospheric pressure. It is the difference between the absolute pressure in a system and the atmospheric pressure, allowing for a clearer understanding of how much pressure is exerted by a gas or liquid in a given environment. This type of pressure is commonly used in various applications, such as tire pressure and pressure measurement in fluid systems, to reflect the actual pressure exerted without atmospheric influences.
Does gauge pressure include atmospheric pressure?
Yes, gauge pressure includes atmospheric pressure. Gauge pressure is the pressure measured above atmospheric pressure, so it accounts for the atmospheric pressure as a reference point.
How do you determine the atmospheric pressure using Boyle's law?
To determine atmospheric pressure using Boyle's law, you need to measure the volume and pressure of a gas when it is in equilibrium with the atmosphere. By rearranging Boyle's law equation (P1V1 = P2V2) and substituting the known values, you can solve for the atmospheric pressure. The initial pressure (P1) will be the pressure of the gas in the apparatus, and the final pressure (P2) will be the atmospheric pressure pushing on the gas.
What is the difference between gauge pressure and atmospheric pressure?
Gauge pressure is the pressure measured relative to atmospheric pressure, while atmospheric pressure is the pressure exerted by the Earth's atmosphere on a surface. Gauge pressure accounts for atmospheric pressure, while atmospheric pressure is the total pressure exerted by the atmosphere.
What is a 1013mb?
it's the standard pressure at which all pilots set their altimeter, when communicating Fight Levels.
