Electronic thermometers cost more than their mercury offer comparable accuracy. Different types of Thermometers are classified according to their needs, and accordingly, the maximum temperature and least count are altered. We look at Littmann and other. These trace gases have a combined atmospheric pressure of about 10-14 bar (one-quadrillionth of Earths atmospheric pressure). Temperatures can be taken orally, rectally, or under the arm. Answer (1 of 2): Mercury thermometer was first invented by physicist Daniel Gabriel Fahrenheit in 1714. Readings can be affected by external factors, including drafts, wind, indoor heating, and direct sunlight. This means that Mercury has a spin-orbit resonance of 3:2, which means that it completes three rotations on its axis for every two orbits around the Sun. Most free phone apps designed to take temperature readings are meant for recording the temperature of environments, not people.
