Having the liquid thermometer move up a narrow bore helps to magnify even small changes in temperature, making the measurements more accurate. It also allows for a greater range of temperatures to be measured within a smaller physical space. Additionally, the narrow bore provides a consistent and uniform environment for the liquid to expand or contract in response to temperature changes.

What is the advantage of having the liquid move up a narrow bore?
Having the liquid move up a narrow bore can create capillary action, where the liquid is drawn upwards against gravity. This can help in applications like microfluidics and lab-on-a-chip devices by allowing for precise control and manipulation of small volumes of liquids.
What is the function of the bore in a thermometer?
The bore in a thermometer is the narrow tube where the liquid (mercury or alcohol) expands and contracts with temperature changes. This expansion and contraction of the liquid in the bore allows the thermometer to measure and display the temperature accurately.
Why there is a narrow bend in a thermomter?
The narrow bend in a thermometer, called the constriction, helps to trap and hold the liquid within the bulb of the thermometer as it expands and contracts with changes in temperature. This constriction also acts as a barrier to prevent the liquid from flowing back into the bulb when the thermometer is tilted or turned upside down.
What is the principle used in constructing a liquid thermometer?
The principle behind a liquid thermometer is thermal expansion. As the temperature increases, the liquid inside the thermometer expands, causing it to rise in the narrow tube, giving a reading of the temperature.
How the liquid in a thermometer change so that it can be used to measure a temperature?
The liquid in a thermometer expands and contracts as the temperature changes. This causes the liquid to rise or fall in a narrow tube connected to the bulb of the thermometer. The markings on the tube indicate the temperature based on how high or low the liquid level is.
What is a thermometer bore?
A bore refers to the extremely fine or narrow tube found in a thermometer. It is called a narrow bore or a capillary.

Why is the thread of a thermometer narrow?
The narrow thread of a thermometer allows it to respond more quickly to changes in temperature. This design ensures that the thermometer provides a more accurate reading by allowing the liquid inside to expand or contract faster in response to temperature changes.
What are the characteristics of the liquid used in a liquid in a glass thermometer?
The liquid in a glass thermometer is typically a non-toxic and non-reactive liquid such as mercury or colored alcohol. These liquids have a high coefficient of thermal expansion, allowing them to accurately measure temperature changes by expanding or contracting within the narrow capillary tube of the thermometer.
How is a thermometer used to measure temperature accurately?
A thermometer is used to measure temperature accurately by containing a liquid that expands and contracts with changes in temperature. The liquid rises or falls in a narrow tube, showing the temperature on a scale. The thermometer is calibrated to ensure accurate readings.
How does a liquid thermometer works?
A liquid thermometer works based on the principle of thermal expansion. As the temperature increases, the liquid inside the thermometer expands and rises in the narrow tube, indicating a higher temperature. Conversely, as the temperature decreases, the liquid contracts and falls, showing a lower temperature.
Why is a bore of thermometer so narrow?
The bore of a thermometer is narrow to ensure a quick and accurate response to temperature changes, as the narrow bore reduces the amount of mercury or other liquid needed to fill it. A narrow bore also allows for more precise temperature readings, especially when measuring small temperature differences.
What s the advantage of having a liquid move up a narrow bore?
Capillary action allows liquids to move up a narrow bore due to the adhesive forces between the liquid and the bore surface. This phenomenon is useful in applications such as blood tests, where small volumes of liquid need to be accurately measured without a pump.
