The thermometer works on the principle of thermal expansion and thermal contraction
The answer is: right
The scale known as a thermometer is one of the most widely used tools for measuring temperature.
The scale works on the principle of thermal expansion and thermal contraction, and contains a liquid substance that changes in volume depending on the temperature.
Thus, the user can measure the temperature of the body or the surroundings accurately and appropriately.
The scale can also be used in several other fields, such as medicine, industry and laboratories.
It is hoped that this valuable tool will continue to be useful and used in many applications in the future.
