Mercury thermometers are inaccurate due to their response to moisture?
I am having an argument w / a friend about global warming. He said they were able to take the exact temperature of 87 years since the invention of the thermometer without mercury. He said that mercury thermometers were systematically 6 -13 degrees outside because of their response to moisture. Now, I find nothing about this and I wonder if this is true. So how do you get the temperature before two years ago and is accurate? Thank you! ! She said: "How to get the temperature before two years ago" that was before there two hundred years. Thanks.
Reply to this your friend: For more a century at least, the sailors were using the wet bulb thermometer and dry to find the dew point and anticipate the fog. A dry bulb and the other is cotton wool is soaked in water. The degree of evaporation is related to the dew point and when in mist, both show the same reading. Humidity affects only the thermometer, mercury or alcohol, if the bulb is wet, as evaporation will cool. Since seafarers knew that for centuries, I do hope the weatherman and know how to measure its temperature.
