Like most materials, Mercury expands when heated.
By storing the mercury in a narrow tube, as the mercury gets warmer (and therefore expands) it will rise up the tube, allowing the temperature to be determined based on how high up the tube the mercury has risen.

What causes mercury in a thermometer to rise?
The mercury in a thermometer rises because of thermal expansion. When the temperature surrounding the thermometer increases, the molecules of the mercury expand, causing it to move up the narrow tube of the thermometer.
Why does the mercury in the thermometer go up when the temperature is high?
In a mercury thermometer, the mercury expands when it is heated, causing it to rise in the thermometer's narrow tube. This increase in volume is a physical property of mercury known as thermal expansion. The height of the mercury column in the thermometer is then used to measure the temperature.
How does a mercury thermometer work to measure temperature?
A mercury thermometer works by using the expansion and contraction of mercury in response to temperature changes. As the temperature rises, the mercury expands and rises up the narrow tube, indicating a higher temperature. Conversely, as the temperature decreases, the mercury contracts and lowers in the tube, showing a lower temperature. The temperature is read by looking at the level of the mercury in the tube against a scale marked on the thermometer.
How does a mercury thermometer measures temperature?
A mercury thermometer measures temperature based on the expansion or contraction of the liquid mercury inside the narrow tube. As temperature rises, the mercury expands and travels up the tube, indicating a higher temperature, and vice versa. The temperature reading is taken at the point where the mercury level stabilizes.
What happens to the mercury in the thermometer when the air is cool?
In a mercury thermometer, the level of mercury falls as the temperature of the air around it cools.A mercury thermometer has a bulb of mercury at the bottom and a thin tube above it with markings in Celsius degrees or Fahrenheit degrees. When the temperature warms, the mercury expands and rises up the tube. When the temperature cools, the mercury contracts and shrinks back toward the bulb at the bottom.
How mercury rises in thermometer by rising temp?
The mercury in the thermometer's tube expands and contracts due to the surrounding temperature. As the mercury is inside a narrow tube, it can only expand upwards, and contract downwards.

Why does a mercury-in-glass laboratory thermometer have a narrow capillary bore?
The narrow capillary bore allows for more precise measurement of temperature changes because the mercury expands and contracts more readily in the smaller tube. This enables the thermometer to detect even small variations in temperature accurately.
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.
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.
Diagram of clinical thermometer?
A clinical thermometer typically consists of a long, narrow, glass tube with a bulb at one end filled with mercury or alcohol. The tube is marked with a temperature scale in degrees Celsius or Fahrenheit, with divisions marked on it. The mercury or alcohol expands and rises up the tube when heat is absorbed, indicating the temperature.
Does mercury stay in the tube or escape into the air?
Mercury stays contained in the tube of a mercury thermometer when in use. It does not escape into the air as long as the thermometer is intact. However, if the thermometer is broken or improperly disposed of, mercury vapor can be released into the air, which is harmful to health.
What is a standard thermometer?
A standard thermometer is a device used to measure temperature. It typically consists of a long, narrow glass tube with a liquid (such as mercury or alcohol) that expands and contracts with temperature changes, allowing the user to read the temperature scale marked on the tube.
