Best Answer

There are several ways:

  • use a liquid whose coefficient of thermal expansion is near constant,
  • use a liquid with low vapour pressure,
  • use a bulb with a relatively larger bulb and thinner stem,
  • calibrate the thermometer carefully.

What is a laboratory thermometer?

A laboratory thermometer is used to check the temperature, or changes in temperature, of an object with precise accuracy.


How should you do to increase the accuracy of the thermometer?

using a thin capillary bore using a thick glass stem


What is liquid-in-glass thermometer?

A liquid-in-glass thermometer is a type of thermometer that consists of a glass tube filled with a liquid, typically mercury or alcohol, which expands or contracts with changes in temperature. The level of the liquid in the tube corresponds to the temperature, allowing for temperature measurement.


Which device has a liquid in glass components?

thermometer


What makes a liquid-in-glass thermometer sensitive to a small change of temperature?

A liquid-in-glass thermometer is sensitive to small temperature changes because the liquid inside expands and contracts with changes in temperature. This expansion and contraction leads to a noticeable movement of the liquid in the narrow capillary tube, making it easier to detect even small temperature changes. Additionally, the glass tube and thinness of the liquid column increase the sensitivity of the thermometer.


What is the effect of mineral impurities of the upper and lower fixed point of a mercury-in-glass thermometer?

Mineral impurities in the upper fixed point of a mercury-in-glass thermometer can lead to an increase in the boiling point of the liquid, affecting the accuracy of high temperature measurements. Impurities in the lower fixed point can similarly impact the freezing point, affecting the accuracy of low temperature readings. Regular calibration and cleaning can help mitigate these effects.


Why does the expansion of glass in liquid-in - glass thermometer ignored?

The expansion of the glass in a liquid-in-glass thermometer is generally ignored because the expansion coefficient of glass is relatively small compared to that of the liquid inside it. The expansion of the glass is minimal compared to the expansion of the liquid, so it has little impact on the overall accuracy of the thermometer readings.


Why does liquid inside a thermometer rise as the temperature s increase?

As the temperature increases, the kinetic energy of the liquid molecules also increases, causing them to move more rapidly and spread out. This increase in motion leads to an expansion of the liquid, causing it to rise in the narrow tube of the thermometer.


What are the materials in a thermometer?

For a classic thermometer: glass and mercury, colored ethanol or another liquid.


Why are the thermometers called liquid in glass thermometers?

Liquid-in-glass thermometers are called so because they contain a liquid (usually mercury or alcohol) enclosed in a glass tube. When the temperature changes, the liquid expands or contracts, moving up or down the tube to indicate the temperature.

What are the characteristics of the liquid used in a liquid in glass thermometer?

The liquid in a liquid-in-glass thermometer is typically a colored alcohol, such as ethanol or dyed ethanol, to aid in visibility. It has a low freezing point to ensure it remains in liquid form within the thermometer's temperature range, and it expands and contracts uniformly with temperature changes for accurate readings.
