Alcohol has a lower freezing point than Mercury, making it suitable for use in lower temperature environments. Additionally, alcohol is less toxic than mercury, making it safer in case of accidental exposure. Alcohol is also a good conductor of heat and has a larger coefficient of expansion, allowing for a more responsive and accurate temperature measurement in laboratory settings.
What else can I help you with?
Some laboratory thermometer use alcohol instead of mercury what are the advantages and disadvantges of using alcohol in thermometer?
Advantages of using alcohol in a thermometer include being less toxic than mercury, having a lower freezing point, and a wider temperature range. However, disadvantages include having a lower boiling point than mercury, being more flammable, and having a lower density which can affect accuracy.
Why is mercury used in clinical thermometer and not laboratory thermometer?
Mercury is no longer used much in thermometers due to the poisonous compounds that it forms. When I grew up, in Chemistry at school and at the doctors there were mercury thermometers and alcohol thermometers.
Who invented the mercury and alcohol thermometers?
Daniel Gabriel Fahrenheit invented the mercury thermometer. Ferdinand II invented a thermometer using alcohol but it was very inaccurate.
What is the liquid in a thermometer?
It can range from mercury to alcohol it depends on the manufacturer.
Is it a solid liquid or gas found in a thermometer?
Actually anything that won't freeze or boil at the operating range of the thermometer. The most common are mercury and alcohol.
Define a laboratory thermometer in 2 sentences.?
A laboratory thermometer is a device for measuring temperature ranges. It can take the form of a manual (mercury or alcohol) or electronic (digtal).
Some laboratory thermometer use alcohol instead of mercury what are the advantages and disadvantges of using alcohol in thermometer?
Advantages of using alcohol in a thermometer include being less toxic than mercury, having a lower freezing point, and a wider temperature range. However, disadvantages include having a lower boiling point than mercury, being more flammable, and having a lower density which can affect accuracy.
What else can be used in a thermometer instead of mercury?
Alcohol, usually with a red dye in it
What is in the laboratory thermometer?
There are many kinds of thermometer in use. Liquid in glass thermometers usually contain alcohol (dyed red or blue) or mercury (silvery coloured).
What liquids are used in thermometer?
Mercury and alcohol
What type of Thermometer is most likely to contain alcohol?
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.
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 is alcohol found in the school's thermometer instead of mercury?
Because the thermal expansion is higher from alcohol (ethanol) and then it's more precise.
Does a Kelvin thermometer contain mercury or alcohol?
There is no mechanical difference between a kelvin thermometer and any other kind so I think it would be the same as other thermometers i.e. Alcohol (because it is not as dangerous as mercury)
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.
What is in liquid in thermometer?
mostly Mercury but there are some with alcohol
What is the tip of a laboratory thermometer called?
The tip of a laboratory thermometer is called the bulb. It contains the temperature-sensitive element, usually mercury or alcohol, which expands and contracts based on changes in temperature, allowing for accurate temperature readings.
