Temperature Concepts Questions

Multiple choice

What is the temperature range of a clinical thermometer?

  1. 35oC to 42oC

  2. <font size="2">94oC to 100</font><sup style="font-size:" small;="">o<font size="2">C</font>

  3. 10oC to 100oC

  4. 30oC to 40oC
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The temperature range of a clinical thermometer is 35oC to 42oC. It is because the clinical thermometer is designed to measure the temperature of a human body only. The temperature of the human body normally does not go below 35oC or above 42oC.

Multiple choice

The normal temperature of the human body is

  1. 98.4o

  2. 99.4o

  3. 96.60

  4. 99.5o
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Normal human body temperature ranges from 97.7°F to 99.5°F, with an average around 98.2-98.4°F based on modern studies. The commonly cited 98.6°F was based on an outdated 1851 study.

Multiple choice

Directions: A certain city is served by subway lines A,B and C and numbers 1 2 and 3 When it snows , morning service on B is delayed When it rains or snows , service on A, 2 and 3 are delayed both in the morning and afternoon When temp. falls below 30 degrees Fahrenheit afternoon service is cancelled in either the A line or the 3 line, but not both. When the temperature rises over 90 degrees Fahrenheit, the afternoon service is cancelled in either the line C or the 3 line but not both. When the service on the A line is delayed or cancelled, service on the C line which connects the A line, is delayed. When service on the 3 line is cancelled, service on the B line which connects the 3 line is delayed On which of the following occasions would service be on the greatest number of lines disrupted.

  1. A snowy afternoon with the temperature at 45 degree farenheit

  2. A snowy morning with the temperature at 45 degree farenheit

  3. A rainy afternoon with the temperature at 45 degree farenheit

  4. A rainy afternoon with the temperature at 95 degree farenheit
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A snowy morning at 45°F causes delays on: B (snow morning rule), A, 2, 3 (rain/snow rule). Since A is delayed, C is also delayed (connection rule). This affects 5 lines total. A rainy afternoon at 95°F would affect fewer lines, and options with 45°F afternoon don't trigger the maximum cascade of effects.

Multiple choice

Pasteurisation is the process in which milk is heated to

  1. 60° C for 10 minutes

  2. 63° C for 20 minutes

  3. 63° C for 30 minutes

  4. 72° C for 10 minutes
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Pasteurization of milk typically involves heating to 63°C for 30 minutes (low-temperature long-time method) or 72°C for 15 seconds (high-temperature short-time method). The goal is to kill harmful bacteria while preserving nutritional quality and flavor.

Multiple choice

The optimum condition for BOD measurement is

  1. 25 degree centigrade / light / 5d

  2. 25 degree centigrade / dark / 5d

  3. 30 degree centigrade / dark / 5d

  4. 30 degree centigrade / light / 5d
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The optimum condition for BOD measurement is 25 degree centigrade / dark / 5d.

Multiple choice

The normal temperature of the human body is

  1. 44oF

  2. 38oF

  3. 96oF

  4. 98.4oF
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Normal human body temperature is 98.6°F (37°C), approximately 98.4°F as given in the option. 44°F and 96°F are too low, while 38°F is near room temperature. The narrow range around 98.6°F maintains optimal enzyme function.

Multiple choice

The normal temperature of human body is

  1. 400 F

  2. 400 C

  3. 1000 F

  4. 370 C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The normal human body temperature is approximately 37°C (98.6°F), though it can vary slightly between individuals and throughout the day. This is the temperature at which human biological processes function optimally.

Multiple choice

What is the normal temperature of a human body?

  1. 98.4° C

  2. 98.4° F

  3. 100° C

  4. 200° F
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Normal human body temperature is approximately 98.6°F (37°C). Option B (98.4°F) is the closest to this standard value. The other options are implausible: 98.4°C would be boiling hot, 100°C is the boiling point of water, and 200°F would be fatal.

Multiple choice

Match the column I with column II.

 
Column I
Column II
(a) Psychrophiles (i) grow optimum at around 60oC
(b) Psychrotrophs (ii) grow optimum at 80oC or higher (archaea)
(c) Mesophiles (iii) grow at 0oC, but optimum is about 15oC
(d) Thermophiles (iv) grow best at moderate around 37oC
(e) Hyperthermophiles (v) grow at 0oC also, but optimum is 20 - 30oC

  1. (a) - i, (b) - iv, (c) - v, (d) - ii, (e) - iii

  2. (a) - v, (b) - i, (c) - iv, (d) - iii, (e) - ii

  3. (a) - ii, (b) - iii, (c) - i, (d) - v, (e) - iv

  4. (a) - iv, (b) - ii, (c) - iii, (d) - i, (e) - ii

  5. (a) - iii, (b) - v, (c) - iv, (d) - i, (e) - ii
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Correct answer. (a) Psychrophiles (Cold Loving) can grow at 0° C, but optimum is about 15° C. (b) Psychrotrophs can grow at 0° C also, but optimum is 20 - 30° C – important in food spoilage. (c) Mesophiles(Moderate temperature loving) grow best at moderate around 37° C – many pathogens fall in this category. (d) Thermophiles (Heat Loving) have a growth optimum at around 60° C. (e) Hyperthermophiles have growth optima of 80° C or higher (archaea).
