Because that will mess with the temperature reading on the thermometer. And it would be dangerous if the thermometer is broken as there are dangerous chemicals (i.e.mercury) inside.
When a thermometer is placed into something cold, the liquid inside contracts and decreases in volume. This causes the liquid level to decrease, indicating a lower temperature on the scale of the thermometer.
When a thermometer is exposed to warmth, the liquid inside it expands and rises up the tube. This is because heat causes the molecules in the liquid to move faster, taking up more space and causing the volume to increase. The expansion of the liquid is used to measure the temperature.
The red liquid in a liquid-in-glass thermometer is mineral spirits or ethanol alcohol mixed with red dye. A grey or silver liquid inside the thermometer is mercury. Mercury thermometers are not used anymore due to the dangers associated with mercury.
It is important not to let the thermometer rest on the bottom of the beaker because the bottom can be heated unevenly leading to inaccurate temperature readings. Placing the thermometer in the liquid away from the bottom ensures a more accurate measurement of the liquid's temperature.
Mercury the liquid inside thermometer is mercury.. but it is called thermometric liquid.
When the liquid in the thermometer gets warmer it expands.

The liquid in a Galilean thermometer is usually a clear alcohol, such as ethanol or methanol.
The liquid in a Galileo thermometer is usually a clear, alcohol-based solution.
the liguid inside the thermometer is Mercury.
This depends on the thermometer model.
The liquid typically used in a Galilean thermometer is colored alcohol.
The liquid inside the thermometer "contracts" when it is placed into something cold. This means that it decreases in volume and increases in density. This is the reason that the thermometer can measure heat: the volume of the liquid inside the thermometer changes as a function of heat, and the amount of liquid in the "tube" of the thermometer changes as a function of volume. Because of this relationship, the level of the liquid in the tube of the thermometer changes as a function of heat.
Because that will mess with the temperature reading on the thermometer. And it would be dangerous if the thermometer is broken as there are dangerous chemicals (i.e.mercury) inside.
A liquid-in-glass thermometer is a type of thermometer that consists of a glass tube filled with a liquid, typically mercury or alcohol, which expands or contracts with changes in temperature. The level of the liquid in the tube corresponds to the temperature, allowing for temperature measurement.
The liquid in a clinical thermometer is often mercury. But there are thermometers that use a coloured alcohol.
