Mercury is very toxic and can cause nerve damage and once it enters the body is just about impossible to get out. Alcohol is a much less hazardous substance. Even though it can be toxic, the body easily breaks it down in low doses.
.
Also, alcohol is commercially more abundant and less expensive than mercury.
If the liquid is silver, it is liquid mercury (Hg). If the liquid is red, it is coloured ethyl alcohol (C2H5OH).
The liquid in a thermometer is typically mercury or alcohol. Mercury is commonly used in traditional thermometers, while newer digital thermometers may use alcohol. These liquids expand and contract with temperature changes, allowing the thermometer to measure the temperature accurately.
alcohol, such as ethanol or dyed ethyl alcohol. Mercury and alcohol are both used in thermometers due to their ability to expand and contract with temperature changes, allowing accurate measurement of thermal fluctuations. Mercury is less common now due to its toxicity.
Because of its properties. It freezes at 0 Celsius, and boils at 100 Celsius. WHen it freezes, it expands slightly - putting pressure on the vessel it's stored in. If it was used in thermometers... (a) you cold only measure a temperature range of between 5 and 95 degrees Celsius.
Alcohol is a safer choice for a thermometer liquid as it is not as toxic as mercury, making it safer for both human health and the environment. Mercury can be harmful if it leaks or is accidentally ingested, whereas alcohol is less harmful if exposed.
what are the qualities of mercury over alchoholic as thermometric liquid
Thermometric substances are materials that are sensitive to changes in temperature and can be used to measure it. Examples include mercury, alcohol, and liquid crystal.
Alcohol is preferred as a thermometric liquid substance due to its wide range of liquid state temperatures, which allows for accurate measurement across a broad spectrum. Additionally, alcohol has a low freezing point, making it suitable for use in cold environments. Its low viscosity ensures quick and consistent response to temperature changes, making it a reliable choice for various thermometric applications.
Mercury the liquid inside thermometer is mercury.. but it is called thermometric liquid.
Thermometric liquid is a liquid used in thermometers to measure temperature changes. Common examples include mercury and colored alcohol, which expand or contract in response to temperature variations, allowing for precise readings. The choice of thermometric liquid depends on the temperature range and the desired accuracy of the thermometer. Mercury is often used for high-temperature measurements, while alcohol is favored for lower temperatures due to its lower freezing point.
The red liquid in a liquid-in-glass thermometer is mineral spirits or ethanol alcohol mixed with red dye. A grey or silver liquid inside the thermometer is mercury. Mercury thermometers are not used anymore due to the dangers associated with mercury.
Thermometric liquid is the liquid found in the thermometer that help in the up and down movement of the temperature.
Some times red coloured liquid is used but mostly gray coloured liquid is used.
They change from a liquid to a vapor (gas).
mostly Mercury but there are some with alcohol
Mercury is considered an ideal thermometric liquid because it has a wide temperature range over which it remains a liquid, from -39°C to 356°C. It also has a high thermal conductivity, making it respond quickly to temperature changes. Additionally, it has a uniform coefficient of expansion, leading to consistent and accurate temperature measurements.
If the liquid is silver, it is liquid mercury (Hg). If the liquid is red, it is coloured ethyl alcohol (C2H5OH).
