A rise in temp causes the expansion of the Mercury or alcohol present in the tube.The graduation is done in such a way that the amount of expansion gives the temp.

A rise in temperature causes the particles in the thermometer to move faster, which in turn causes the liquid to expand and rise in the thermometer tube. This increase in volume is then calibrated to display a corresponding temperature reading.

How does the alchohol thermometer works?

An alcohol thermometer operates based on the principle that alcohol expands when heated and contracts when cooled. The liquid alcohol inside the thermometer expands up the tube as the temperature rises and contracts as the temperature drops, allowing for temperature measurement based on the level of the liquid in the tube.


What is the working principle of a liquid in glass thermometer?

A liquid-in-glass thermometer works based on the principle of thermal expansion. As temperature increases, the liquid inside the thermometer expands and rises in the calibrated glass tube. The level of the liquid indicates the temperature which corresponds with a specific scale on the thermometer.


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.


How does a thermometer work?

A thermometer works by measuring the temperature of an object or environment using a liquid or metal that expands or contracts with changes in temperature. This causes the level of the liquid or the length of the metal to change, which is then converted into a temperature reading on a scale.


How does an electrical thermometer works?

An electrical thermometer works by measuring changes in electrical resistance as temperature changes. This change in resistance is then converted into a temperature reading. The resistance of the sensor in the thermometer varies with temperature, allowing for accurate temperature measurements.
