Mercury has a high boiling point and can measure high temperatures.alcohol has a low freezing point and can measure measure very low temperatures.so to accurately measure very high and also very low temperatures both are used.

What is in a thermometer besides Mercury?

Some thermometers use alcohol or dyed alcohols like ethanol instead of mercury. These liquids expand and contract with temperature changes, allowing the thermometer to measure the temperature. Digital thermometers use electronic sensors to measure temperature.


Differences between mercury and alcohol thermometers?

Alcohol is used to measure at low temperatures because it has a lower freezing point than Mercury. Mercury has a higher boiling point than alcohol, mercury boils at around 400 Co and alcohol boils around 80 C0.


What is a non mercury thermometers?

A non-mercury thermometer is a thermometer that does not contain mercury as the temperature-sensing liquid. Instead, it may use alcohol, galinstan, or other materials to measure temperature. These alternatives are considered safer for environmental and health reasons compared to mercury thermometers.


What two substances are used in the thermometer's glass tube?

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.


What metal is use in thermoter?

Thermometers typically use a metal such as mercury or alcohol to measure temperature. Mercury thermometers are commonly used in applications such as medical settings, while alcohol thermometers are used in environmental monitoring due to their lower environmental impact.

What was used in thermometers in 1600 instead of mercury?

Before the use of mercury, alcohol (usually ethanol or dyed spirits) was commonly used in thermometers. Alcohol thermometers were popular because alcohol has a lower freezing point than mercury, making them suitable for a wider range of temperatures.


What do they use instead of mercury thermometer?

Digital thermometers, infrared thermometers, and alcohol or galinstan thermometers are commonly used as alternatives to mercury thermometers due to the environmental and health risks associated with mercury.


What is used in thermometers now instead of mercury?

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.


Why alcohol used instead of mercury in modern thermometers?

Alcohol is used in modern thermometers instead of mercury because it is less toxic and poses less of a health and environmental risk if the thermometer breaks. Additionally, alcohol has a lower freezing point than mercury, allowing it to measure lower temperatures accurately.


Why alcohol used in laboratory thermometers instead of mercury?

Alcohol-based thermometers are used in labs because alcohol has a lower freezing point than mercury, making them suitable for lower temperature measurements. Additionally, alcohol is less toxic than mercury, reducing potential health and safety risks in laboratory settings.

Why can't you use mercury thermometers?

Mercury is toxic and poses serious health and environmental risks if the thermometer were to break. Safer alternatives, such as digital thermometers or alcohol-filled thermometers, are now commonly used instead.


What are the two substance used in liquid column thermometers?

iodine and Mercury


Why is Mercury used in thermometers instead of alcohol?

Mercury thermometers have advantages over alcohol thermometers. The liquid is visible making the results easy to read. It expands at a regular interval. It measures temperature quickly and accurately.


Before mercury what was used to fill thermometers?

Water was initially used and later on alcohol was used.
