 Believe
it or not, the Galileo thermometer works because the principle of
buoyancy or resilience. Buoyancy is the factor that makes an object
float or sink in a liquid substance. For example: a steel boat can
float, whereas a steel pipe will sink.
Here is a little history about the Galileo thermometer:
1. A Galileo thermometer is designed primarily of a sealed glass
cylinder.
2. The cylinder of a Galileo thermometer contains a clear liquid
substance inside.
3. The liquid carries a certain number of weights.
4. Sometimes the liquid of a Galileo thermometer is colored for
an overall effect that is more pleasing to the eye.
5. As the liquid in a Galileo thermometer changes because of
temperature it also conforms its density. Therefore the suspended
weight will rise and fall in order to remain at the same density
as the surrounding liquid—measuring temperature.
6. If the weights of a Galileo thermometer differ—even
by a slight amount, and the least dense of the liquid is at the
top and most dense part of the liquid is at the bottom, together
they form a scale for measuring the temperature.
There are several complex ideas behind a Galileo thermometer that
we will not go into here because of the scientific complexity of
it. Nonetheless, now you know a bit more about the Galileo thermometer
and what it does—as well as a little bit of how it does what
it does.
In basic summation: if the mass is greater than the mass of liquid,
an object will sink, not float. However, if mass is less than mass
of liquid, the object will float.
