When temperature goes up the liquid expands. The liquid then takes up more space and you see this as a rise in scale on the thermometer. The same applies vise versa
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.
