Expansion is used in a thermometer to measure temperature changes. As temperature increases, the liquid (like Mercury or alcohol) inside the thermometer expands and rises up the tube, indicating a higher temperature. Conversely, when temperature decreases, the liquid contracts and moves down the tube, showing a lower temperature.

What is an alcohol thermometer used for?
An alcohol thermometer is used to measure temperature by the expansion and contraction of the alcohol in the thermometer's tube. It is commonly used in lab settings, homes, and industries to measure temperature accurately within a specific range.
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.
What is the function of thermometer mercury?
The Mercury expands with temperature. Since expansion is linear over the normal range of a mercury-driven thermometer, the level of mercury within a little glass tube indicates the current temperature of the thermometer's immediate environment.
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.
Why does Mercury in the the thermometer rise?
Mercury rises in a thermometer when the temperature increases because mercury expands as it heats up. This expansion of the mercury column inside the thermometer is used to measure the temperature of the surrounding environment.
What is an alcohol thermometer used for?
An alcohol thermometer is used to measure temperature by the expansion and contraction of the alcohol in the thermometer's tube. It is commonly used in lab settings, homes, and industries to measure temperature accurately within a specific range.

Which poisonous metal was once used in thermometer due to its properties of expansion in heat?
Mercury.

What is mercury used for in a thermometer?
The thermal expansion of mercury is proportional and linear to temperature.
What is used to measure temperature?
Temperature is usually measured via expansion/contraction of a liquid (liquid thermometer), differences in expansion/contraction of two metals (bi-metallic strip thermometer), changes in electrical resistance (thermistor or thermocouple) or radiant energy (for example: a pyrometer)
Why does Mercury in the the thermometer rise?
Mercury rises in a thermometer when the temperature increases because mercury expands as it heats up. This expansion of the mercury column inside the thermometer is used to measure the temperature of the surrounding environment.
How does thermal expansion relate to a thermometer?
Thermal expansion refers to the increase in size of a substance as its temperature rises. In a thermometer, thermal expansion is utilized by materials such as mercury or alcohol to expand and contract based on temperature changes, allowing the thermometer to measure and display the temperature.
Explain how the common thermometer works by expansion?
A common thermometer works by using a liquid like mercury or colored alcohol that expands when heated and contracts when cooled. This expansion and contraction is used to measure temperature changes and is visualized through a scale on the thermometer, which gives a reading based on the level of liquid inside.
What happen to the mercury in a thermometer when the temperature increase?
When the temperature increases, the mercury in a thermometer expands and rises up the column because the volume of the liquid increases with temperature. This expansion is linear and is used to indicate the rise in temperature on the thermometer scale.
