They are cheaper an they don't pose the same environmental risks when broken.
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.
Is it safe to use rubbing alcohol in a simple thermometer?
No, it is not safe to use rubbing alcohol in a simple thermometer. Rubbing alcohol is a disinfectant and can affect the accuracy of the thermometer readings. It is recommended to use a thermometer as per the manufacturer's instructions.
What does alcohol in a thermometer rise in a result of?
The rise in alcohol in a thermometer is a result of the expansion of the alcohol due to increased temperature. As the temperature increases, the molecules in the alcohol move faster and spread out, causing the liquid to rise in the thermometer tube.
How does alcohol in a thermometer work?
Alcohol in a thermometer expands when heated and contracts when cooled. This change in volume causes the level of alcohol in the thermometer to rise or fall. By measuring the level of the alcohol, the temperature of the substance being measured can be determined.
Why does alcohol in a thermometer rise?
Alcohol in a thermometer rises whenever the temperature of its surrounding increases. As the temperature increases, the heat causes the alcohol to expand ever so slightly, which shows up as an increase of height of the alcohol in the tube of the thermometer.
What's the liquid in a Galileo thermometer?
The liquid in a Galileo thermometer is usually a clear alcohol, such as ethanol or isopropyl alcohol.
Why the alcohol level in a thermometer goes down when it's cold?
When the temperature drops, the alcohol in the thermometer contracts and takes up less space. This results in the alcohol level appearing to go down in the thermometer.
What are the advantages and disadvantages of using alcohol in a thermometer?
The advantages are:They are cheap.They can be seen clearly as they are in red in color.They are thermomatric liquids.The disadvantages are:They wet the surface.They have less surface tension.They have less density.
What is the advantage and disadvantage of using alcohol in thermometer?
u don't have to flick the thermometer to reset the temperature reading when you use an alcohol based thermometer (unlike a mercury thermometer where you have to flick and flick and flick flick flick that thermometer for the mercury to be reset so that you can make an accurate reading) a disadvantage is that the alcohol thermometer is slightly less acurate The biggest advantage is that alcohol is not nearly as toxic as mercury, so that if the thermometer breaks, you won't be poisoned.
What liquids are used in thermometer?
Mercury and alcohol
What is an alcohol thermometer used for?
An alcohol thermometer is used to measure temperature by the expansion and contraction of the alcohol in the thermometer's tube. It is commonly used in lab settings, homes, and industries to measure temperature accurately within a specific range.
Where can you get an alcohol thermometer?
in a drunken man
