It has a narrow glass tube which has e

* filled with a liquid farlier, mercury was
used but, as it is harmful for us, it has been
replaced with alcohol. The rest of the volume
of the tube has vacuum and its other and is
closed The bulb is kept in contact with the
object whose temperature is to be measured
so that its temperature becomes same as that
of the object Because of the increased
temperature the alcohol inside it expands
and its level in the tube rises. Using the
properties of the expansion of alcohol (to be
discussed below), the temperature can be
obtained from the level of the alcohol. The
tube of the thermometer is marked
accordingly
Figure 144 (b) shows a clinical
thermometer. As the body temperature of a
healthy person is 37 C, clinical thermometers
are designed to measure temperatures
between 35 C and 42°C. These days, instead
