What does Mercury think of temperature?

1. Hold the tail of the thermometer by hand and turn the thermometer to the middle position between the degree and scale. When you turn it gently and repeatedly, you will see a mercury line.

2. Hold the tail of the thermometer and gently shake the thermometer to make the thermometer scale lower than 35 degrees.

3. Then put it under your arm (in silver) 10- 15 minutes and take it out.

4. See where the silver line goes along the gap between the scale and the degree, and the corresponding indicator is the actual temperature.

Mercury thermometer is an expansion thermometer. Mercury has a freezing point of -39℃, a boiling point of 356.7℃ and a measuring temperature range of -39℃-357℃, so it can only be used as an instrument for local supervision. Using it to measure temperature is not only simple and intuitive, but also can avoid the error of external remote thermometer. The thermometer is of Mitsubishi structure, with fonts on both sides, one side marked with production date and brand, the other side marked with degree and the other side marked with scale.
