What do you think of mercury thermometer?

1. Thermometer is of Mitsubishi structure, with fonts on both sides, one of which is marked with production date and brand, the other with degree and the other with scale.

2. The thermometer has a scale of 14 squares from 35 degrees to 42 degrees, each square represents 0.5 degrees and is divided into five squares of 0. 1 degree.

3. After taking the thermometer, hold the tail of the thermometer by hand and turn the thermometer to the middle of the degree and scale.

Turn it gently and repeatedly, and you will see a silver line (mercury). Look a little longer and you'll know.

5. Hold the tail of the thermometer, gently shake the thermometer to make the thermometer scale below 35 degrees, and then put it under your arm (in silver) 10- 15 minutes later.

6. Follow the gap between the scale and the degree to see where the silver line goes. The current temperature is 36.4 degrees.
