Do the both alcohol and mercury thermometers give the same reading of 60'C at same atmospheric conditions. if their distance between two points are exactly divided to 100 parts?

If you could measure precisely enough, they would be slightly different, but both have coefficients of thermal expansion that are close enough to linear that you probably would not be able to see the difference visually. Keep in mind that the boiling point of the liquid used in alcohol thermometers may not be too far off from 60 °C so if you set one of your points too close to the boiling point (or above it), you will get skewed graduations.

How long does it take a car traveling 40 mph to come to a complete stop?
For a car with good brakes and a length of 4m, a dry road with a driver with average reaction time it will take approximately 36m/118 feet/nine car lengths for it to stop. This can be divided up into two sections the thinking distance/reaction distance of 12m and a braking distance of 24m. Like the previous answer stated the braking distance can be changed depending on the road surface type and weather conditions or if the car is fitted with an Anti-lock Braking System Thinking distance can be increased by drinking alcohol or taking some types of drugs.
Why is alcohol 70 percent?
Isopropyl rubbing alcohol is usually around 70% (by volume) because this is the optimum concentration for its action as a disinfectant. At lower concentrations it is not as effective. However at higher concentrations its effectiveness declines because of the way in which it works. Alcohol kills cells in the target organisms by causing the coagulation of proteins which it contacts. If very strong alcohol is used then it penetrates the cell wall of the organism and coagulates the proteins which are immediately inside the cell wall and this mass of coagulated protein protects the inner parts of the cell from the alcohol. Then, if conditions improve, the cell can recover. Alcohol which is less concentrated works in the same way but because it coagulates the proteins more slowly, more of the alcohol is able to penetrate deeper into the cell and so is more effective in destroying the cell.
What is this Alcohol 8 oz?
"Alcohol 8 oz" refers to a serving size of alcohol that is 8 ounces in volume. The term "alcohol" typically refers to alcoholic beverages, such as beer, wine, or spirits. It is important to note that consuming alcohol should be done responsibly and in moderation.
Can 33 percent alcohol kill you?
If you drink too much of it, yes. You can get alcohol poisoning from any percentage alcohol if you drink too much of it.
How many ounces of a 25 percent alcohol solution must be mixed with 9 ounces of a 30 percent alcohol solution to make a 28 percent alcohol solution?
Let a be the number of ounces of 25% alcohol required. Then, 25a + (30x9) = 28(9 + a) 25a + 270 = 252 + 28a 3a = 18 a = 6 Then 6 ounces of 25% alcohol + 9 ounces of 30% alcohol produces 15 ounces of 28% alcohol.
Why is Mercury used in thermometers instead of alcohol?
Mercury has a higher coefficient of expansion compared to alcohol, which leads to a more precise measurement of temperature. Mercury is also less affected by changes in atmospheric pressure and does not evaporate easily, making it a more reliable substance for use in thermometers.
What are 3 main different types of thermometers?
The three main types of thermometers are liquid-in-glass thermometers, digital thermometers, and infrared thermometers. Liquid-in-glass thermometers use a liquid like mercury or alcohol to measure temperature, digital thermometers provide a numeric temperature reading, and infrared thermometers measure temperature from a distance using infrared technology.
Why are alcohol thermometers preferred in cold countries?
Alcohol thermometers are preferred in cold countries because they have a lower freezing point compared to mercury thermometers, so they can accurately measure temperatures in colder conditions without freezing and causing damage. Additionally, alcohol thermometers are safer to use as they do not contain toxic mercury, which is important for environmental and health reasons.
What is the difference between alcohol thermometers and digital thermometers?
Alcohol thermometers use a liquid such as ethanol to measure temperature based on the expansion of the liquid, while digital thermometers use electronic sensors to detect temperature changes and provide a numerical reading. Digital thermometers tend to be more accurate and easier to read than alcohol thermometers.
What different kinds of thermometers are there?
There are 34 different types of thermometer that range from alcohol thermometers and ear thermometers to medical thermometers and electrical resistance thermometers.
What are two liquids that have been used in thermometers?
Mercury and alcohol (typically ethanol or dyed alcohol) are two liquids that have been commonly used in thermometers. Mercury is often used in industrial thermometers due to its high thermal conductivity, while alcohol is used in household thermometers for safety reasons.
Why rubbing alcohol is used in thermometers?
no
What are used in thermometers?
Mercury and alcohol
Where are alcohol thermometers used?

What are the two substance used in liquid column thermometers?
iodine and Mercury
Why mountaineers carry alcohol thermometer with them rather than mercury thermometer?
Mountaineers carry alcohol thermometers because they are less likely to break at high altitudes due to their flexibility, making them more durable for rugged conditions. Additionally, alcohol thermometers are safer in case of accidental breakage, as they do not contain toxic mercury like traditional mercury thermometers.
Can alcohol be used in a thermometer?
Yes, it can and you can purchase thermometers which use alcohol.
