Multiple choice physics heat - measurement thermometers application of various thermometric scales different types of thermometers

Before using the clinical thermometer mercury level should be below:

  1. $ 45 ^\circ C$
  2. $ 35 ^\circ C$
  3. $ 95 ^\circ C$
  4. $ 55 ^\circ C$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The mercury level should be below $35^{o}C$ or $94^{o}F$, because minimum temperature of human body can not be below $35^{o}C$. Hence, it must be at lowest level to measure the temperature of human body correctly.

What is the limit of temperatures human body can achieve?

  1. $25^oC$ to $42^oC$
  2. $35^oC$ to $42^oC$
  3. $35^oC$ to $62^oC$
  4. $5^oC$ to $42^oC$
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Normal human body temperature, also known as normothermia or euthermia, is the typical temperature range found in humans. The normal human body temperature range is typically stated as $36.5–37.5 °C (97.7–99.5 °F).$
The limit of temperatures human body can achieve is $35^oC $ to $62^oC$

Choose the correct option

  1. Temperature of a water kept inside a beaker is measured when the laboratory thermometer is held inside the water

  2. Temperature of a water kept inside a beaker is measured when the laboratory thermometer is removed from the water

  3. Temperature of our body is measured when the clinical thermometer is kept inside the mouth

  4. Temperature of our body is measured when the clinical thermometer is removed from the mouth
Reveal answer Fill a bubble to check yourself
A,D Correct answer
Explanation
A.Temperature of a water kept inside a beaker is measured when the laboratory thermometer is held inside the water.This gives accurately the temperature of water in beaker.
B
Temperature of a water kept inside a beaker is measured when the laboratory thermometer is removed from the water.This method is wrong as thermometer reading will be drop as it removed from the beaker.Hence this will give error in reading.
C
Temperature of our body is measured when the clinical thermometer is kept inside the mouth.In the clinical thermometers the maximum temperature is first allowed to reach then we remove the thermometer and  take the reading.Hence temperature inside mouth gives error in reading 
D
Temperature of our body is measured when the clinical thermometer is removed from the mouth.In the clinical thermometers the maximum temperature is first allowed to reach then we remove the thermometer and  take the reading.Hence this method is correct.

Which of the following is not true about Laboratory thermometers ?

  1. Laboratory thermometers are used to measure temperatures with a high degree of precision.

  2. Laboratory thermometers are used to measure body temperature.

  3. Range of laboratory thermometer is -10C to 110C

  4. Laboratory thermometers are designed for lab purposes such as checking boiling point, freezing point etc.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A laboratory thermometer is a tool used in laboratories to measure temperature with high accuracy. It can be partially or fully immersed in the substance being measured. A laboratory thermometer is recognizable by its long stem with a silver bulb at the end. The silver color in the bulb normally indicates the presence of mercury. Mercury expands as the temperature increases, thus raising the reading, while decreasing temperatures contract the mercury, lowering the reading. Mercury-in-glass thermometers are less used in the 21st century as preference is shifted to other types of thermometers, such as digital, alcohol-filled and organic-based thermometers.

hence,Laboratory thermometers are $not$ used to measure body temperature.

Which of the following is the range of temperature recorded by a laboratory thermometer ?

  1. $0^oC$ to $100^oC$
  2. $-10^oC$ to $110^oC$
  3. $30^oC$ to $120^oC$
  4. $45^oC$ to $145^oC$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A laboratory thermometer is used for measuring temperatures other than the human body temperature. It ranges from -10˚C to 110˚C. Laboratory thermometers are designed for lab purposes such as checking boiling point, freezing point, or temperature of other substances

A clinical thermometer reads temperature from

  1. $35^oC to \ 42^oC$
  2. $0^oC to \ 100^oC$
  3. $25^oC to \ 42^oC$
  4. $35^oC to \ 62^oC$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
A clinical thermometer is a thermometer used to measure human body temperature. Most made in $20th$ century are mercury-in-glass thermometers. They are very sensitive as mercury level rises very fast with small variation in temperature most of these thermometers shows Celsius and Fahrenheit ( medical thermometer ) scales and runs from $35°C$ to $42°C.$
Hence, the answer is $35°C$ to $42°C.$

When a mercury thermometer is inserted in a pot of hot water and the reading is recorded , what temperature is being 

  1. Average temperature of water and surroundings

  2. Average temperature of thermometer

  3. Average temperature of water and thermometer

  4. Temperature difference between water and surroundings
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In this process, thermal equilibrium will eventually be reached after inserting the thermometer in hot pot. Hence heat is transferred from the water to the thermometer.

Normallly the body temperature of healthy person is ______ Degree celcius?

  1. 25

  2. 37

  3. 30

  4. 32
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Normally the body temperature of healthy person is $37^oC$ or ($98.6^oF$)
It is scientific fact that normal body temperature of a healthy body is $37^oC$. Apparently it is the perfect balance as it's warm enough to prevent fungal infection but not so hot that we need to eat non-stop to maintain out metabolism.
