WebDec 8, 2024 · The Galileo thermometer works because of the principle of buoyancy, which states that objects that are denser than their surroundings sink, and objects that are less dense than their surroundings float. The temperature surrounding the thermometer will make the liquid in the thermometer more dense as it cools, or less dense as it heats up. WebIt consists of a glass column with mercury and inches markings on it. The top end of the tube is closed, and the bottom end is rested in a cup containing mercury known as a cistern. To increase the accuracy, these barometers are corrected for ambient temperature and the local value of gravity.
WebOct 25, 2008 · The simplest kind of barometer is a tall closed tube standing upside down in a bath of mercury (a dense liquid metal at room temperature) so the liquid rises partly up the tube a bit like it does in a thermometer.
