Describe the process and precautions necessary for using a laboratory thermometer.
✓
Answer
The thermometer should be handled carefully, avoiding any impact that could cause breakage. The bulb of the thermometer should be immersed in the liquid of which the temperature is being measured. The bulb of the thermometer should not touch the sides or bottom of the container.
The thermometer must be held vertically. The temperature should be read keeping the eye in line with the level liquid in the thermometer.The reading of the temperature must be taken immediately after the level of liquid in the column of the thermometer stops moving up. Temperature of the liquid may change if we hold on for long, before taking reading.After taking the reading while the thermometer is still immersed, it should be cleaned and stored properly to maintain its accuracy and longevity.
