A medical thermometer (also called clinical thermometer) is
used for measuring human or animal body temperature
.
What is the function and uses of thermometer?
A thermometer is a tool that
measures temperature — how hot or cold something is
. Thermometers are used to see if you have a fever or tell you how cold it is outside. Made up of thermo (heat) and meter (measuring device), the meaning of the word thermometer is pretty straightforward.
What is the function of constriction in a clinical thermometer?
Answer:
to stop the Mercury from falling off when it is taken out of our mouth
.
What are the four uses of thermometer?
–
To measure the outdoor temperature.
– To measure body temperature during a physical exam at the doctors. – To measure body temperature when someone is ill to determine if he/she has a fever. – To measure the temperature of an oven.
What is the most important use of thermometer?
Thermometers are used
to measure the temperature
and this is a very important part of weather forecasting. Many thermometers come in a glass tube that contains a liquid, usually mercury or alcohol. The liquid expands when it's hotter and contracts when it is colder.
What is the main function of constriction?
Constriction is a narrowing or closing of a passageway. Constriction is a
key regulation step for many different processes in the body
, and is usually coupled with dilation, which is an opening or widening of a structure or passageway to facilitate the needs of the body under given conditions.
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 are the 10 uses of thermometer?
- They can be used to measure air temperatures.
- Recording data over a perod of time means that changes in the climate could be observed.
- The temperatures are shown both in centigrade and fahrenheit.
What are the types of clinical thermometer?
- Digital thermometers. …
- Ear (or tympanic) thermometers. …
- Infared thermometers. …
- Strip-type thermometers. …
- Mercury thermometers.
What are the parts of a clinical thermometer?
The main parts of a mercury thermometer are
the capillary, the bulb, the scale, and the expansion chamber
.
What is the function of alcohol in alcohol thermometer?
An alcohol thermometer is a thermometer which utilizes
the expansion and contraction of alcohol in response to temperature changes to measure the temperature
. A number of different alcohols can be used, depending on the environment where the thermometer is being utilized, with ethanol being among the most common.
What is constriction in clinical thermometer called?
Answer:
cliniccal thermometer

What are the physical properties of clinical thermometer?
A clinical thermometer made up of a long narrow, uniform glass tube.
It has a bulb at one end which contains shining liquid mercury. Outside the bulb
, a small thread can be seen in which mercury can flow. It has a scale marked from 35°C to 42°C.
What are the 2 important things that he does upon using thermometer?
A thermometer has two important elements: (1)
a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer)
in which some change occurs with a change in temperature; and (2) some means of converting this change into a numerical value (e.g. the visible scale …
What is the principle on which a clinical thermometer is based?
Explanation: A thermometer works on the principle that
solids and liquids expand on heating
. As the temperature rises, mercury expands causing it to move upwards and depict the temperature.
What is difference between clinical thermometer and laboratory thermometer?
Clinical thermometer is used to
measure the human body temperature
. A laboratory thermometer is not used for this purpose of measuring body temperature; it is generally used for the measurement of objects which generally have a temperature range outside that of a normal human body.
What is the difference between digital thermometer and clinical thermometer?
A clinical thermometer is for taking body range temperatures, a laboratory thermometer is for use in a lab, with a broad range of temperatures for various applications, A digital thermometer has a digital readout so it is easy to read,
almost any thermometer can be digital
, clinical and laboratory thermometers can be …
What is clinical thermometer explain with diagram?
: a
thermometer for measuring body temperature that
has a constriction in the tube above the bulb preventing movement of the column of liquid downward once it has reached its maximum temperature so that it continues to indicate the maximum temperature until the liquid is shaken back down into the bulb.
How do clinical thermometers differ from each other?
The clinical thermometer
is used to measure body temperature
, however, laboratory thermometer is not used for the purpose of measuring body temperature. The temperature range of clinical thermometers is 35°C to 42°C and that of laboratory thermometers is -10°C to 110°C.
What is the function of the mercury in a clinical thermometer?
In a mercury thermometer, a glass tube is filled with mercury and a standard temperature scale is marked on the tube. With changes in temperature, the mercury expands and contracts, and the temperature can be read from the scale. Mercury thermometers
can be used to determine body, liquid, and vapor temperature
.
What are the advantages of clinical thermometer?
The advantages of these types of thermometers is that they
are cheap, easy to read, can be submerged in liquids
, require very little maintenance and are reliable. The disadvantages are that they break easily and there is risk of mercury poisoning if the glass tube breaks.
Which liquid is used in clinical thermometer?
Mercury
-in-glass thermometers have been considered the most accurate liquid-filled types. However, mercury is a toxic heavy metal, and mercury has only been used in clinical thermometers if protected from breakage of the tube.
Why ethanol is used in thermometer?
Unlike the mercury-in-glass thermometer, the contents of an alcohol thermometer are less toxic and will evaporate quickly. The ethanol version is the most widely used due
to the low cost and relatively low hazard posed by the liquid in case of breakage
.
Why does the capillary of a clinical thermometer have a kink?
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 does arrow mark on thermometer mean?
The long lines on the thermometer are one degree. … All glass thermometers are marked with an arrow which points to
98.6
(Considered to be the normal adult temperature).
What is clinical thermometer short answer?
Your answer : A clinical thermometer is
a thermometer used to measure human body temperature
. Most made in the 20th century are mercury-in-glass thermometer. They are accurate and sensitive, having a narrow place where mercury level rises very fast. A kink in the tube stops the mercury level from falling on its own.
Why clinical thermometer has a construction near the bulb?
A thermometer used to measure the temperature of human body. A clinical thermometer has
a constriction near the bulb
in it. Due to this, mercury thread does not fall on removing the bulb from the mouth of the patient. … This helps the mercury in the bulb to acquire the patient's temperature more quickly and precisely.
What is the working principle of thermometer?
These liquid thermometers are based on the principal of
thermal expansion
. When a substance gets hotter, it expands to a greater volume. Nearly all substances exhibit this behavior of thermal expansion. It is the basis of the design and operation of thermometers.
