Mercury in a thermometer expands and contracts with changes in temperature. As the temperature rises, the mercury expands and rises in the tube, and as the temperature falls, the mercury contracts and lowers in the tube. This movement is then converted into a temperature reading on the scale of the thermometer, allowing for accurate temperature measurement.

How does a thermometer measure temperature accurately?
A thermometer measures temperature accurately by using a substance that expands or contracts with changes in temperature, such as mercury or alcohol. As the substance expands or contracts, it moves along a scale to indicate the temperature. The thermometer is calibrated to ensure accurate readings.
What instrument measures room temperature?
A thermometer is commonly used to measure room temperature. There are different types of thermometers, such as digital thermometers or mercury thermometers, that can be used to accurately measure the temperature of a room.
What does a thermometer do to measure temperature accurately?
A thermometer measures temperature accurately by using a liquid, such as mercury or alcohol, that expands or contracts based on the temperature. This causes the liquid to rise or fall in a narrow tube, which is marked with a scale to show the temperature.
Is temperature measured by using a thermometer?
Yes, temperature is typically measured using a thermometer. Thermometers come in various types, such as digital, mercury, or infrared, to accurately measure temperature in different settings.
What are three different sorts of thermomenters?
Mercury thermometer: uses the expansion of mercury to measure temperature. Digital thermometer: uses electronic sensors to quickly and accurately measure temperature. Infrared thermometer: measures temperature by detecting the infrared energy emitted by an object.
What is the substance in a thermometer that tells us the temperature?
The substance in a thermometer that tells us the temperature is usually mercury or alcohol. These substances expand or contract in response to temperature changes, allowing the thermometer to measure the temperature accurately.

What is least count for thermometer?
The least count of a thermometer is the smallest temperature difference that it can measure accurately. Typically, for a standard mercury-in-glass thermometer, the least count is 0.1°C.
Why was the mercury thermometer invented?
The mercury thermometer was invented as a way to accurately measure temperature by using the expansion of mercury in response to changes in temperature. This allowed for precise and consistent temperature readings, making it a useful tool in various fields such as medicine, research, and industry.
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.
How to read a mercury thermometer accurately?
To read a mercury thermometer accurately, hold it at eye level and make sure the mercury level is below your body temperature. Wait for a few minutes for the mercury to stabilize, then read the temperature at the point where the mercury stops. Be sure to note the temperature in whole numbers and avoid parallax errors by looking straight at the thermometer.
What is the working principle of the mercury thermometer?
Mercury thermometers work on the principle that mercury expands when heated and contracts when cooled. The scale on the thermometer is calibrated based on this expansion and contraction, allowing it to measure temperature accurately. When the temperature rises, the mercury expands and rises up the tube, and when the temperature falls, the mercury contracts and moves back down the tube.
