a temperature-measurement device whose operation is based on the thermal expansion of a liquid. Liquid-filled thermometers provide a direct reading of the temperature.
-- Bring thermometer into room. -- Wave it around in the air of the room for a minute or two. -- Do not hold the thermometer in your hand or breathe on it. -- Wait a while for the room temperature to get through the thermometer glass. -- Look through the glass at the sliver of liquid inside the thermometer. Find the end of the liquid, and see what number is marked on the glass at the same level. That number is your room temperature.
Thermometer
Air temperature is usually measured using a thermometer. There are various types of thermometers available for measuring air temperature, such as liquid-in-glass thermometers, digital thermometers, and thermocouples. The most common unit of measurement for air temperature is degrees Celsius or Fahrenheit.
Mercury expands on heating.so at noon when the sun is overhead in the thermometer the Mercury expands and pushes the index down.And then the alcohol which is half filled in the maximum tube rises.then the max.temp is taken.
When the liquid is heated (by the environment), the particles in the liquid have more energy, and start moving around more, which causes the liquid to expand and take up more room. Conversely, in cold temperatures, the particles do not have as much energy, and do not move as much, so the liquid contracts.
A liquid-in-glass thermometer is a type of thermometer that consists of a glass tube filled with a liquid, typically mercury or alcohol, which expands or contracts with changes in temperature. The level of the liquid in the tube corresponds to the temperature, allowing for temperature measurement.
Thermometer
A Galileo thermometer is a thermometer made of a sealed glass cylinder containing a clear liquid and a series of objects whose densities are such that they rise or fall as the temperature changes.

a lab thermometer did not have a constriction as compared to clinical thermometer. it have a wide range of measurement and usually contains alcohol
A thermometer used to measure air temperature uses a glass tube filled with a liquid either alcohol or mercury. When the temperature increases the particles of liquid expand, filling the glass tub. Thermometers that are used to measure you body temperature uses infrared sensors.
A Galileo thermometer contains liquid-filled glass bulbs of different densities. As the temperature changes, the bulbs rise or sink in the liquid, indicating the temperature. This works because the density of the liquid changes with temperature, causing the bulbs to move accordingly.
For a classic thermometer: glass and mercury, colored ethanol or another liquid.
A so-called "glass" thermometer has a small bore-hole in the center of the glass that has some liquid in it. It's the activity of the liquid in the narrow hole that makes the thermometer a thermometer.
There was something called a Galileo thermometer that was completely different than the modern mercury thermometer. The Galileo thermometer is a glass cylinder filled with clear liquid in which a series of globes floats. The globes are filled with different colored liquid and have tags hanging on them with temperatures written on the tabs. You read it by looking to see which globes are floating and which are sinking.
Galileo Galilei was the first to invent the thermometer formerly known as thermoscope in 1592.
