household thermometers has designed and manufactured a variety of thermometers according to the purpose of use. The basis of its design is: using the phenomenon that solids, liquids, and gases are affected by temperature and expand with heat and contract with cold; under constant volume conditions, the pressure of gas (or steam) changes due to different temperatures; the effect of thermoelectric effect; resistance varies with Changes due to changes in temperature; effects of heat radiation, etc.
When using a thermometer to measure the temperature of a liquid, the correct method is as follows:
1. First observe the range, division value and 0 point, and the temperature of the measured liquid cannot exceed the range;
2. The glass bubbles of household thermometers are all immersed in the liquid on the side, and do not touch the bottom or wall of the container;
3. After the glass bubble of household thermometers is immersed in the liquid to be tested, wait for a while, and wait for the thermometer to stabilize before reading;
4. When reading, the glass bulb of the thermometer should remain in the liquid, and the line of sight should be level with the upper surface of the liquid column in the thermometer.
The manufacturer of household thermometers reminds you to pay attention: do not shake it before measuring the temperature.
