How do you increase sensitivity of mercury in glass thermometer?

Sensitivity of a thermometer is the length of increase of the liquid per degree rise in temperature. More sensitive means more noticeable expansion. So if you want to increase the sensitivity, you could have a thinner capillary tube, a larger thermometer bulb etc. :)sailesh

∙ 14y ago1.Ensure that the glass at the bulb is thing so that heat energy can be transferred between the thermometer and the substance more rapidly
2.Ensure that the diameter of the capillary tube is small. In this way, a smaller expansion in the mercury causes a large linear expansion in the capillary tube.

Why does a mercury-in-glass laboratory thermometer have a narrow capillary bore?
To increase the sensitivity of the thermometer, that is, for the thermometer to respond quickly to small changes in temperature.
Which thermometer is a greater health hazard if it breaks Is it the mercury in glass or alcohol in glass thermometer?
Mercury is poisonous.
Who invented the Mercury thermameter?
A mercury-in-glass thermometer, invented by German physicist Daniel Gabriel Fahrenheit, is a thermometer consisting of mercury in a glass tube. Calibrated marks on the tube allow the temperature to be read by the length of the mercury within the tube, which varies according to the heat given to it. To increase the sensitivity, there is usually a bulb of mercury at the end of the thermometer which contains most of the mercury; expansion and contraction of this volume of mercury is then amplified in the much narrower bore of the tube. The space above the mercury may be filled with nitrogen or it may be less than atmospheric pressure, which is normally known as a vacuum.
What is constant in mercury- in- glass thermometer?
volume of the mercury
What is liquid-in-glass thermometer?
what do they use for the liquid in glass ball thermometer
Why is the stem of a thermometer made up of glass?
Because Mercury expands in heat, it is more accurate than other elements used in thermometers.
Who element used of the glass tube of clinical thermometer to measure thermometer?
mercury
Who invented Mercury-in-glass thermometer?
German physicist Daniel gabriel Fahrenheit invented the mercury-in-glass thermometer
What is the signal conditioner of mercury-in-glass thermometer?
The capillary tube of the thermometer ( in case of a mecury thermometer).
What is the sensor in mercury in glass thermometer?
Temperature Sensor
Is the external bulb of a thermometer also made of mercury?
The red liquid in a thermometer is Mercury, which is usually encased in a glass tube
What is the sSensor in Mercury-in-glass thermometer?
The sensor is just the mercury, a liquid metal.
