What else can I help you with?
Would have it be possible to make mercury thermometers if expansion of glass is greater than the expansion of mercury?
Suppose so, but the mercury would fall, instead of rising with temperature increase.
Would have it be possible to make thermometer if expansion of glass would have been greater than mercury?
Great question to think about ! Seems to me that if the expansion of glass were greater than the expansion of mercury, then you could easily make thermometers. But when you calibrated them, they would turn out different from what we have now, because the warmer temperatures would be marked lower on the glass, and the cooler temperatures would be marked higher on the glass.
Where do humans make use of expansion?
thermometers (liquid mercury)
What is the purpose of mercury thermometers?
Mercury thermometers are used to measure temperature accurately. The expansion of mercury in the glass tube allows for easy visualization of temperature changes. However, due to the toxic nature of mercury, these thermometers are being phased out in favor of digital thermometers.
What is the difference between digital and mercury thermometer?
Digital thermometers measure electrical resistance and Mercury thermometers measure thermal expansion.
What are some advantages of using mercury thermometers?
mercury has better thermoconductiity and they have a greater range of readings
Compare the expansion of mercury with alcohol?
Mercury expands more evenly than alcohol. This is why thermometers that contain mercury are more accurate than those that contain alcohol. However, alcohol freezes at a temperature much lower than mercury, so it is better used in thermometers in extreme cold conditions.
Why mercury is used in milk?
Mercury is highly poisonous and should not be used in milk production. The only place where mercury might be used in milk production is in mercury thermometers and where possible, these should be replaced with alcohol thermometers.
Which poisonous metal was once used in thermometers due to its properties of expansion In heat?
Mercury.
Can mercury and alcohol mixed to become a thermometer?
Mercury and alcohol are not the thermometers but the liquids found in the thermometer they have different properties that make them uniqe for example alcohol is safe while mercury is poisonous,alcohol does not expand uniformly but has great expansion while mercury expands uniformly and has low expansion,alcohol is cheap while mercury is expensive,alcohol wets the glass while mercury does not.so alcohol can not combine to form a thermometer simply because they are the liquids found in it and not the thermometer itself.
Why is Mercury used in old thermometers?
Mercury was used in old thermometers because mercury expands when it reaches a certain temperature, so it was a really good "gauge". Now, they stopped making thermometers with mercury as the liquid since it was very poisonous. i hope you liked the answer!
Is mercury present in all types thermometers?
No, mercury is not present in all types of thermometers. While mercury thermometers are common, other types such as digital thermometers and infrared thermometers do not contain mercury. Mercury thermometers are being phased out due to environmental concerns.
