Mercury freezes at around -39°C, so it cannot be used to measure temperatures below that point. In very cold regions where temperatures can drop significantly lower than this, mercury thermometers would not be accurate or reliable. Furthermore, mercury is also toxic, posing health and environmental risks if the thermometer were to break in such harsh conditions.
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.
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.
The liquid in a clinical thermometer is called mercury. It is used to measure body temperature by expanding and rising within the thermometer.
A digital thermometer uses electronic sensors to measure temperature and displays the reading digitally, while a mercury thermometer uses a column of mercury to measure temperature and has a calibrated scale to indicate the temperature. Digital thermometers are often faster and more accurate than mercury thermometers, and are also safer since they do not contain mercury.
A thermometer should be used to measure the temperature of liquid. Digital thermometers are more accurate and quicker to read than traditional mercury thermometers. Make sure to choose a thermometer that is suitable for measuring liquid temperatures specifically.

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.
A thermometer is used to measure temperature. It typically consists of a bulb containing mercury or alcohol that expands or contracts depending on the temperature. The scale on the thermometer then indicates the temperature.
We cannot use a clinical thermometer to measure temperature of a candle flame because then the mercury will expand too much and the thermometer will explode.
