What type of liquid is used in a thermometer?
What type of liquid is used in a thermometer?
Mercury
Mercury is one of the most familiar materials used in liquid thermometers. Other liquids, such as kerosene or ethanol, may also be used in these types of thermometers. When heat rises, the liquid expands from a bowl or bulb into the empty area, climbing up the tube.
What are three liquids used in thermometers?
The liquid that is contained within the thermometer may be one of many different substances, but the most common are mercury, toluene (or a similar organic substance), and low-hazard biodegradable liquids.
What liquid is used in thermometers and why?
Mercury is the only one in liquid state at room temperature. It’s used in thermometers because it has high coefficient of expansion. Hence, the slightest change in temperature is notable when it’s used in a thermometer. It also has a high boiling point which makes it very suitable to measure higher temperatures.
What are the 2 liquid in a thermometer?
There are two major types of Liquid-in-glass thermometers which are mentioned below: Mercury Thermometers. Alcohol Thermometers.
Are there different types of liquid in glass thermometers?
What kind of liquid is used in an alcohol thermometer?
The position of the meniscus shows the temperature against an inscribed scale. The liquid used can be pure ethanol, toluene, kerosene or isoamyl acetate, depending on manufacturer and working temperature range. Since these are transparent, the liquid is made more visible by the addition of a red or blue dye.
What kind of thermometer is filled with Mercury?
Mercury Thermometers. This type of thermometer was developed by a German based physicist named Daniel Gabriel Fahrenheit. It consists of mercury as a liquid filled in a glass tube. On the body of the glass tube, calibrated marks are provided which facilitates the reading of temperature.
Who is the inventor of the liquid in glass thermometer?
