Why do we measure blood pressure in mercury? How do gases differ from liquids? What is fluid mechanics? How does a simple mercury barometer function? How does it show pressure? Why does condensation form most rapidly on the coldest object in a room for example, on a glass of i...
Our fellow, Dr Oday, holding a mercury barometer, that’s > 40 year-old and we used to measure ambient pressure in our PFT lab@InterfaithMed. No one is using a mercury barometer anymore in this digital world@accpchest#CHESTChallenge2019pic.twitter.com/ZprLTsAtJX ...
Generally, mercury is used in a barometer to measure pressure. In the barometer, the mercury column is used to measure pressure. Here, mercury works...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your toug...
Although mercury is known from early times and was used by alchemists, its first modern scientific applications date back to 1643 when Torricelli used it in the barometer to measure pressure and about eight decades later Fahrenheit used it in the thermometer to measure temperature. Before this, me...
To solve the question, "The empty space above mercury in a simple barometer is called '' vacuum," we can follow these steps:1. Understand the Barometer: A barometer is an instrument used to measure atmospheric pressure. It typi
It is the atmospheric pressure that supports a column of mercury 1 millimetre high. The unit is named after Evangelista Torricelli, Italian physicist and mathematician, for his discovery of the principle of the barometer in 1643.Definition: Inch of mercury...
Global warming is a myth If a mercury thermometer breaks, it will evaporate, potentially reaching dangerous levels in indoor air. Hidden hazards in health care A separate observer used a mercury thermometer to measure 3-minute axillary temperatures within a maximum of 20 minutes of the subjective ...
To solve the problem, we need to determine the pressure of the gas in the container using the information provided about the manometer and the atmospheric pressure. 1. Understand the Manometer Setup: A manometer is a device used to measure the pressure of a gas by comparing it to the atmosp...
It then came into my mind what that most careful observer of natural phenomena [Amontons] had written about the correction of the barometer; for he had observed that the height of the column of mercury in the barometer was a little (though sensibly enough) altered by the varying temperature ...
Question: What is the pressure of the gas in the mercury manometer if h = 55 mm and atmospheric pressure is 760 mmHg? A. 815 mmHg B. 760 mmHg C. 55 mmHg Manometer: In fluid mechanics, manometers are the devices used t...
