The idea is based avoiding use of the thermometer when it is reading "higher" than what it is that is being measured. Let's look at what's happening. If we wash a clinical thermometer in hot water, it will respond to that hot water. That will cause the reading to shoot up well above a hundred degrees. If we then try to use it, it will have to "cool down" under the tongue of the person we're using it on. It is actually being cooled by that person. The thermometer will take a relatively long time to reach the temperature of the individual whose temperature is being measured. And this time will vary, but will be longer than it would be for the thermometer to "come up" to temperature. One of the directions for using these thermometers is to first shake it down until it reads less than 95 degrees or so. If you're starting with a thermometer than has just been washed in hot water, you're not going to be able to shake it down per the directions. You'll have to run it under cool water for a bit to cool it so you can use it.

Why does bulb of a clinical thermometer break when placed in very hot water?
becuse alla does it
What happens when you put a clinical thermometer into boiling water?
if its really really hot it will fry but if its just hot then it will just go up really high
Why should not use water in the thermometer?
One of the problems with water in a thermometer is the effect of capillary action - the column of water tends to "stick" to the sides of the thermometer and create a U-shaped surface at the top. This makes it very difficult to read the thermometer. Previously mercury was considered to be a good medium for thermometers, but this has been discontinued due to the health risks from a broken mercury thermometer; the current medium in thermometers is dyed ethanol or methanol.
