why mercury does not fall or rise in a clinical themometer when taken out of the mouth?

thanks

Mercury does not fall or rise in a clinical thermometer when taken out of the mouth because it has a kink near the bulb of the thermometer that prevents mercury level from falling on its own. 

Hope the answer is clear to you.

Cheers!!!

because it is having a kink near the bulb and the kink does not allows the mercury to fall.

the clinical thermometer has a kink near the bulb. the kink prevents the mercury from falling down on its own. laboratory thermometer do not have this feature

mercury does not fall because because it is covered with the coating of glass sheiled

Mercury does not fall because because it is covered with the coating of glass sheiled

well mercury does not fall because in the clinical thermometer the max temprature that can be measured is 35c to 42c and our human temperature will never exeed that as above 42c we are dead!

because their is a kink

as there is a kink or constiction that will slow down the flow of the falling mercury. but if u give the thermometer a jerk the mercury will go back to the bulb

because of the kink
