Question

When marking the fixed points on a thermometer, it is observed that at 0oC,
the mercury thread is of length 1cm and 6cm at 100oC. What temperature would
correspond to a length of 4cm?

Answer 1

The temperature corresponds to a length of 4cm is 80°C.

To find the answer, we need to know about the thermometers.

How to find the temperature corresponds to 4cm?

• An instrument for measuring and indicating temperature, typically one that consists of a short, hermetically sealed glass tube with graduation markings and a mercury or alcohol-filled bulb at one end that expands along the tube as it measures temperature is called Thermometer.
• Given that the temperature coincides with the 1cm line is 0 degree Celsius, and that of 6cm is 100 degrees Celsius.
• Thus, the separation between these two temperatures will be,

                          $d=6cm-1cm=5cm$

• This separation is 5cm, for 100-unit difference of temperature.
• Thus,

                        $1cm=\frac{100}{5}=20^0C$

• Thus, 4cm corresponds to a temperature,

                         $T=4*20=80^0C$

Thus, we can conclude that the 4cm line corresponds to a temperature of 80°C.
