What is barometric pressure measured by?
A barometer measures atmospheric pressure to determine weather or altitude changes.
If the atmospheric pressure is 29.4 inches of mercury what is the corresponding pressure of mercury?
The atmospheric pressure of 29.4 inches of mercury is equivalent to 74.676 millimeters of mercury. This conversion is based on the standard ratio where 1 inch of mercury is equal to 25.4 millimeters of mercury.
What kind of apparatus did Boyle use to determine that relationship?
Boyle demonstrated this relationship using a U-shaped tube sealed at one end. The tube had mercury added to it so that a volume of gas was trapped at the sealed end of the tube; the gas thus was compressed by atmospheric pressure and the pressure from the column of mercury. Boyle poured mercury into the open end of the U-tube and measured the change in volume of the trapped gas as the applied pressure increased.
What units are used to express pressure measurements?
The most common units for expressing pressure measurements are pascals (Pa), bars (bar), and pounds per square inch (psi). Other units such as atmospheres (atm) and millimeters of mercury (mmHg) are also used in specific applications.
Which element is a liquid at 758 K and standard pressure?
Gold is a liquid at 758K and standard pressure.
What can be measured in inches of mercury?
pressure
What can measured in inches of mercury?
pressure
What is air pressure measured to?
It is measured in inches of Mercury, millibars, and hectoPascals.
What does the pressure units in weather mean?
It refers to the atmospheric pressure which, in this case, is measured in inches of Mercury on a mercury barometer
What is vacuum measured in?
vacuum is measured in pressure. To get a vacuum you need a negative pressure. that would be inches of mercury hg
What are the units blood pressure is reported in?
Blood Pressure is measured and reported as a pressure in mm of mercury
What does the pressure units 30.03 in weather mean?
It refers to the atmospheric pressure which, in this case, is measured in inches of mercury on a mercury barometer
How do you measure pressure in a fuel tank?
It is measured in inches of mercury (inHg)
What does Hg stand for in the metric system?
Nothing.Hg is the chemical symbol for Mercury and, under the old system, atmospheric pressure was measured in terms of the height of a column of mercury that it could support. In the SI systems this has been replaced by pressure measured in Pascals. Standard atmospheric pressure is 101325 Pa.
Is temperature measured in centimetres?
NO ... Barometric Pressure is measured in Centimeters or Inches (of Mercury.) Temperature is measured in Degrees Fahrenheit or Degrees Centigrade.
What is used to measure air pressure.?
It is measured in inches of Mercury, millibars, and hectoPascals.
What are inches of vacuum?
Pressure is often measured in inches of mercury when describing barometric pressure in weather reports. This term is also known as "inches of mercury vacuum".
