Question
State similarities and differences between the laboratory thermometer and the clinical thermometer.
✓
Answer
Similarities:
$1)$ Both clinical and laboratory thermometers have long, narrow, uniform glass tubes.
$2)$ The bulbs of both the thermometers have mercury in them.
$3)$ Both have a bulb at one end.
$4)$ Both use Celsius scale on the glass tube.
Differences:
$1)$ The temperature range of clinical thermometers is from $35^\circ C$ to $42^\circ C$ while that of laboratory thermometer is from $−10^\circ C$ to $110^\circ C.$
$2)$ Clinical thermometer is used to measure the temperature of a human body. However, laboratory thermometer cannot be used to measure the temperature of a human body
$3)$ The least count of both the thermometers differs.
$4)$ Unlike clinical thermometer that can be tilted, laboratory thermometer is kept upright while reading the temperature values.
$5)$ Clinical thermometer has a kink near the bulb while there is no kink in the laboratory thermometer. Due to kink mercury does not fall down on its own in clinical thermometer.
