Question

A laboratory thermometer has a slight bend or kink called constriction close to its bulb.

• A. True
• B. False

Answer 1

The correct option is B False

1. A slight bend or kink in the capillary tube of the clinical thermometer near the bulb ensures that the mercury does not move back into the bulb when the thermometer is taken out of a person's mouth for reading.
2. In a laboratory thermometer, the temperature is measured continuously to note temperature change.
3. Thus the continuous movement of mercury is required without any flow break.

Therefore, a laboratory thermometer does not have a kink. The given statement is False.
