Because mercury is toxic, poisonous while alcohol is fairly harmless.
Many modern thermometers use a colored alcohol solution, typically dyed red or blue, instead of mercury. These alcohol solutions have lower toxicity levels than mercury and are safer to use in household and medical applications. Other alternatives include digital thermometers that use thermistors or infrared technology to measure temperature.
If the liquid is silver, it is liquid mercury (Hg). If the liquid is red, it is coloured ethyl alcohol (C2H5OH).
Most modern thermometers no longer use mercury due to its toxicity. Instead, digital thermometers, infrared thermometers, and other types of thermometer technology that do not contain mercury are widely available and recommended for safer use.
Thermometers are typically made using glass, as it is transparent and durable. Mercury or alcohol are commonly used as the liquid inside the glass tube to measure temperature. Some modern thermometers may use digital sensors and components instead of traditional materials.
Mercury was traditionally used in thermometers due to its high thermal conductivity and wide temperature range. However, due to its toxicity, many modern thermometers use a safer alternative such as colored alcohol, which is less harmful to people and the environment.

A mercury-in-glass thermometer is most likely to contain alcohol. However, due to safety concerns, many modern thermometers use alcohol-based solutions or other materials instead of mercury.
Modern thermometers are typically made of materials such as glass, plastic, or metal. The most common type of modern thermometer is the digital thermometer, which includes a temperature sensor and a digital display screen. Other types of modern thermometers may contain mercury or alcohol as the temperature-sensitive material.
Alcohol or mercury are commonly used as the fluids in thermometers. Mercury was commonly used in the past but is being phased out due to its toxicity. Alcohol is a safer alternative that is used in most modern thermometers.
If the liquid is silver, it is liquid mercury (Hg). If the liquid is red, it is coloured ethyl alcohol (C2H5OH).
Modern thermometers are made of alcohol or Mercury, and uses the Fahrenheit scale and the Celsius scale.
Thermometers can be filled with alcohol, which is a less toxic alternative to mercury. Some modern thermometers use digital sensors to measure temperature, eliminating the need for any liquid filling.
Most commonly, the two substances used in a thermometer's glass tube are mercury and alcohol. Mercury is traditionally used in older thermometers, while alcohol (typically colored red) is used in modern thermometers as a safer alternative.
Most modern thermometers no longer use mercury due to its toxicity. Instead, digital thermometers, infrared thermometers, and other types of thermometer technology that do not contain mercury are widely available and recommended for safer use.
If it is a modern version, yes. Most "air temperature" thermometers use colored alcohol mixes instead of mercury (the vapor of which can be very toxic).
Thermometers are typically made using glass, as it is transparent and durable. Mercury or alcohol are commonly used as the liquid inside the glass tube to measure temperature. Some modern thermometers may use digital sensors and components instead of traditional materials.
Mercury is commonly used in thermometers due to its unique properties, such as its ability to expand uniformly with temperature changes. However, due to its toxicity, digital thermometers with safer alternatives like alcohol or gallium are now more widely used.
