Why is constriction needed in a thermometer?
The constriction in the thermometer is to prevent the mercury from dropping back to the bulb when the reading is being taken. It prevents the thermometric substance (Mercury or Alcohol) from running back into the bulb.
Why is constriction kink made near the bulb of a clinical thermometer?
The kink regulates the in and out flow of mercury from the bulb, making the rise and fall in level of mercury in the tube slow. Therefore, the kink near the bulb in a clinical thermometer prevents the level of mercury from falling when taken out of the mouth.
What is the function of the constriction in the capillary tube?
It has a constriction in the fine capillary tube. This constriction prevents the mercury from contracting and flowing back when it is removed from human body (temperature of surroundings being lower). This enables the recording of the maximum temperature of the body without need for haste.
What is the advantage of the constriction found in a clinical thermometer?
Advantage of constriction in clinical thermometer: Prevents the immediate dropping of mercury thread back to the bulb on the removal of thermometer from the patient.
Why it is more important to have a constriction in a clinical thermometer than in a laboratory one?
The main reason is to make it stay at the maximum point so you get an accurate reading. Without the constriction the mercury would drop as soon as it was taken out and couldn’t show the temperature where it was just taken. Answer has 13 votes.
What is the constriction in the clinical thermometer called?
The glass bulb has mercury inside it. Glass tube has a Celsius scale marked on it. It also has a kink (or constriction) in the glass tube just above the bulb containing mercury. The kink is to prevent back flow of mercury into the thermometer bulb when the thermometer is removed from the mouth of the patient.
What is the function of the bent part of a clinical thermometer called constriction?
This thermometer has markings from 35°c to 43°c. It has a slight bend or kink in the stem just above the bulb, this kink is called the constriction which prevents the mercury from falling back all by itself.
Why there is no constriction in Celsius thermometer?
Answer has 43 votes. The main reason is to make it stay at the maximum point so you get an accurate reading. Without the constriction the mercury would drop as soon as it was taken out and couldn’t show the temperature where it was just taken. Answer has 13 votes.
What is the advantage of providing a constriction in clinical thermometer?
What is the constriction of thermometer called?
What is constriction in clinical thermometer called?
Answer: cliniccal thermometer. i hope it helps us to. kason11wd and 5 more users found this answer helpful.
What is the function of the constriction on a thermometer?
The constriction on mercury thermometer helps to retain the measured value..You have to shake it vigorously to take next reading.For example after taking a reading you touch the mercury bulb the temperature reading will not change..If the constriction was not there thermometer will read room temperature.
How does a clinical thermometer work?
A Clinical Thermometer has a very small constriction at the bottom of the column of mercury. As soon as the thermometer is removed from the patient, the mercury column starts to shrink, but the rate of shrinkage is such at the constriction, the mercury column breaks at that point, and the length remaining is taken as the temperature.
What is the constriction in the capillary tube of thermometer?
The constriction in the capillary tube does not allow the mercury to flow back into the bulb when the thermometer is taken out of the patient’s mouth. Why does the clinical thermometer have a constriction?
Why is there a kink in the bulb of a thermometer?
Thus , due to constriction , the temperature of human body can be taken easily and accurately. kink prevents the mercury present in the capillary to fall back in the bulb.
