General Science
The main parts of a mercury thermometer are the capillary, the bulb, the scale, and the expansion chamber.
Secondly, how do you write a clinical thermometer?
A clinical or medical thermometer is a thermometer used to measure human body temperature. Most made in the 20th century are mercury-in-glass thermometers. They are accurate and sensitive, having a narrow place where the mercury level rises very fast. A kink in the tube stops the mercury level from falling on its own.

Similarly one may ask, what are the functions of a clinical thermometer?
A clinical or medical thermometer is a thermometer used to measure human body temperature. Most made in the 20th century are mercury-in-glass thermometers. They are accurate and sensitive, having a narrow place where the mercury level rises very fast.
What are the parts of digital thermometer?
There are several parts that make up a digital thermometer, these include the probe cap, probe tip, probe, power button, hold button, unit change button and the screen display.
What is capillary tube in clinical thermometer?
1. capillary tube – a tube of small internal diameter; holds liquid by capillary action. capillary, capillary tubing. thermometer – measuring instrument for measuring temperature.
What is capillary tube in thermometer?
CTT-01: A capillary tube is used in the thermometer to indicate the temperature scale. … When the temperature changes, the measuring liquid column moves up and down within the capillary hole. Usually the scale of the thermometer is located on the capillary tube.
What is clinical thermometer Class 7 short answer?
The thermometer used for measuring the temperature of human body is called clinical thermometer. A clinical thermometer is used to measure our body temperature by a doctor (or at home). (1) A clinical thermometer consists of a long glass tube having a thin and uniform bore.
What is clinical thermometer explain with diagram Class 7?
It reads temperature from 35°C to 42°C or from 94°F to 108°F. It consists of a long, slender and uniform glass tube with a bulb at one end containing mercury. There is a small shining thread of mercury outside the bulb. There is a kink near the bulb which prevents mercury level from falling on its own.
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.
What is clinical thermometer Ncert?
Clinical thermometer is used to measure our body temperature. The range of this thermometer is from 35°C to 42°C. For other purposes, we use the laboratory thermometers. The range of these thermometers is usually from –10°C to 110°C.
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 main part of 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 SI unit of temperature?
The kelvin is the SI unit of thermodynamic temperature, and one of the seven SI base units. … Unusually in the SI, we also define another unit of temperature, called the degree Celsius (°C).
What is stem in thermometer?
The Stem and Capillary Bore
Magnified glass makes up the outside jacket of the thermometer, which is called the stem. A thin bore inside the stem gives mercury a route of travel as it expands and contracts. The thin bore is called a capillary.
What is the other name of clinical thermometer?
other names for clinical thermometer are MEDICAL THERMOMETER , BASAL THERMOMETER,RACTAL THERMOMETER..
What is the red part of a thermometer called?
The red liquid is Alcohol, usually Ethanol with a small amount of red dye added. Alcohol is used extensively as a thermometer liquid (similar to Mercury thermometers), esp.
What is thermometer and its types?
A thermometer is a device that is used to measure the temperature of a body. Common types of thermometers are Medical thermometers, Infrared thermometers, Mercury thermometers, thermocouple thermometers, laboratory thermometers, Bimetallic strip thermometers, Pyrometers, etc.
What part of a thermometer is mercury?
The bulb is the lowest part of the thermometer, which has a spherical shape. This section of the thermometer acts as a reservoir to hold mercury — a silvery colored, heavy metal on the periodic table of elements. Mercury stays in liquid form when it is in an enclosed container, and maintained at room temperature.
Why are there long and short lines in thermometer?
These vertical (up and down) lines stand for degrees of temperature. Most thermometers have two scales for temperature, Fahrenheit and Celsius. … Each long line is for 1°F temperature. The four shorter lines between each long line are for 0.2°F (two tenths) of a degree of temperature.
Why mercury is used in clinical thermometer?
Mercury is the only one in liquid state at room temperature. It’s used in thermometers because it has high coefficient of expansion. Hence, the slightest change in temperature is notable when it’s used in a thermometer. It also has a high boiling point which makes it very suitable to measure higher temperatures.
