What is 1 atm-?
It's a measure of pressure. Specifically, it's the amount of pressure exerted by the air in the atmosphere at sea level.
The force exerted against the arterial walls when the heart contracts called the?
Systolic Pressure.
What is The pressure exerted against the cell membrane and cell wall known as?
hydrostatic pressure or turgor (same thing)
How does an aneroid barometer measure atmospheric pressure?
A barometer is an instrument used to measure atmospheric pressure. It can measure the pressure exerted by the atmosphere by using water, air, or mercury.An aneroid barometer is a barometer which measures pressure without using fluids!An aneroid barometer is somewhat different and uses a sealed chamber upon which the fluctuating atmospheric pressure acts. Through mechanical means a pointer is moved on a calibrated scale.
Air pressure at sea level?
Atmospheric pressure is defined as the force per unit area exerted against a surface by the weight of air. Air pressure above sea level can be calculated as p = 101325 (1 - 2.25577 10-5 h)5.25588 where p = air pressure (Pa) h = altitude above sea level (m) The standard atmosphere is a unit of pressure and is defined as being equal to 101.325 kPa.
Define atmospheric pressure?
Air pressure is the pressure exerted from the atmosphere
One ATM equals standard ATMospheric pressure at sea level Choose the correct measure of one ATM?
Atmospheric pressure refers to the force per unit area exerted against a surface by the weight of air above that surface in the Earth's atmosphere. The standard atmosphere (symbol: atm) is a unit of pressure at sea level and is equal to 101325 Pascal.
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?
Atmospheric pressure as element of weather?
Atmospheric pressure is the weight of the air or the pressure exerted onto the Earth by the air. Pressure changes can lead to different weather patterns.
What is The pressure exerted by the gas in earths atmosphere called?
autmospheric pressure
Why the higher the elevation the less atmosphere?
the atmospheric pressure can be considered as the pressure, exerted a columnna air over you, you imagine that this column goes from the limits of ammosfera to you, it's great right? the more we climbed the column of air is made smaller for at that the atmospheric pressure decreases.
What is 1 atm-?
It's a measure of pressure. Specifically, it's the amount of pressure exerted by the air in the atmosphere at sea level.
What is the name for pressure caused by the weight of the atmosphere?
Simply put, atmospheric pressure is the force exerted on a measuring point by the weight of the air molecules on top of that point. Standard atmospheric pressure, measured at sea level at 59F or 15C, is used as a reference point and is equal to 29.92 inches of mercury or 1013 millibars of pressure.
Why is the atmospheric pressure is lower at the top of a mountain than in a valley?
Atmospheric pressure is the force per unit area exerted against a surface by the weight of air above that surface in the Earth's atmosphere. In most circumstances atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point. Low pressure areas have less atmospheric mass above their location, whereas high pressure areas have more atmospheric mass above their location. Similarly, as elevation increases there is less overlying atmospheric mass, so that pressure decreases with increasing elevation. A column of air one square inch in cross-section, measured from sea level to the top of the atmosphere, would weigh just over a stone (and a column one square centimetre in cross-section would weigh just over a kilogram).
Why do you mentioning the boiler pressure in 'ata'?
Normal atmospheric pressure is abbreviated as atm. But when computing for the amount of total pressure exerted on an object at a specific depth or elevation, including normal atmospheric pressure, then the abbreviation ata is used. It stands for atmospheric pressure absolute.
Normal atmospheric pressure is enough to support a column of mercury approximately?
Standard pressure is the pressure exerted by a column of mercury exactly 760 mm high. This is called one atmosphere and is approximately the average pressure at sea level.
What is barometric pressure measured by?
A barometer measures atmospheric pressure to determine weather or altitude changes.
