how do clinical thermometers work
Answers
describe the working of clinical thermometer with a labelled diagram ... A thermometer works on the principle that solids and liquids expand on heating. As the temperature rises, mercury expands causing it to move upwards and depict the temperature. ... As the temperature of the bulb rises, the liquid expands up the tube through the constriction.
Answer:
Clinical thermometers are the ones which we use at our home's unlike laboratory thermometers they are smaller in size and easy to carry anywhere.
Like laboratory thermometers they also have a mercury, scale (Celsius or Fahrenheit) and a kink.
As the heat touches the thermometer at the tip the mercury starts rising with increase in temperature and stops at a particular degree to show us the temperature of the object.
You may have a doubt that what makes the mercury stop?
Well... it is due to the most important part of the thermometer, that is the kink. A kink is a kind of stopper (I think, basically they have the same purpose ) which prevents the backflow of the mercury and gives us the exact temperature.
I hope it helps you!
