Multiple choice

100ºC = ____ ºF.

  1. 212

  2. 25

  3. 24

  4. 18

  5. 7
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The formula to convert Celsius to Fahrenheit is F = (C * 9/5) + 32. For 100 degrees Celsius: (100 * 9/5) + 32 = 180 + 32 = 212 degrees Fahrenheit.

Multiple choice

Explanation

The standard average human body temperature is widely recognized as 98.4 degrees Fahrenheit (or 37 degrees Celsius).

Multiple choice

The temperature required in pasteurisation is

  1. 70oC for 60 minutes

  2. 60o-70oC for 30 minutes

  3. 120oC for 60 minutes

  4. 80oC for 60 minutes
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Pasteurization is a heat-treatment process that destroys pathogenic microorganisms in foods and beverages. The temperature required in pasteurization is 60o - 70o C for 30 minutes.

Multiple choice

Which of the following statements is/are not true?

  1. A clinical thermometer reads temperature from – 10°C to 110°C.

  2. The range of a laboratory thermometer is generally from 35° to 42°C.

  3. The thermometer that measures our body temperature is called a clinical thermometer.

  4. Both (1) and (2)
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

 A clinical thermometer reads temperature from 35°C to 42°C. Also, the range of a laboratory thermometer is generally from – 10°C to 110°C.

Multiple choice

Which of the following is an incorrect way of reading a clinical thermometer?

  1. We should hold the thermometer by the bulb while reading it.

  2. We should ensure that before use, the mercury level is below 35°C.

  3. We should wash the thermometer, preferably with an antiseptic solution before use.

  4. We should read the thermometer keeping the level of mercury along the line of sight.

A Correct answer
Explanation

We should not hold the thermometer by its bulb while reading it.

Multiple choice

Which of the following is a limitation of clinical thermometer?

  1. It cannot measure the temperature of the human body correctly.

  2. It is very difficult to read a clinical thermometer.

  3. It cannot be used to measure the temperatures above 42°C.

  4. There is no limitation of clinical thermometer.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

We cannot use clinical thermometer for measuring the temperatures above 42°C. It may break when kept in the sun or near a flame.

Multiple choice

Directions: This question presents a sentence, all or part of which is underlined. Beneath the sentence you will find five ways of phrasing the underlined part. The first of these repeats the original; the other four are different. If you think the original is best, choose the first answer; otherwise choose one of the others.

Saturday's maximum temperature was 44.2 degrees Celsius, four notches over what is average for this time of the season, while the minimum was six notches above average at 33.2 degrees.

  1. Saturday's maximum temperature was 44.2 degrees Celsius, four notches over what is average for this time of the season, while the minimum was six notches above average at 33.2 degrees.

  2. Saturdays maximum temperature was 44.2 degrees Celsius, four notches above what is average for this time of the season, while the minimum was six notches above average at 33.2 degrees.

  3. Saturday's maximum temperature was 44.2 degrees Celsius, four notches above what is average for that time of the season, while the minimum was six notches above average at 33.2 degrees.

  4. Saturday's maximum temperature was 44.2 degrees Celsius, four notches above what is average for this time of the season, while the minimum was six notches above average at 33.2 degrees.

  5. Saturday's maximum temperature was 44.2 degrees Celsius, four notches above what is average for this time of season, while the minimum was six notches above average at 33.2 degrees.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

(A) is incorrect because of wrong preposition use 'over' (which means above from one end to another) instead of 'above' (which means over the head). (B) is incorrect because of error of punctuation. (Saturday's is written as Saturdays) (C) is incorrect because of usage of 'that' in place of 'this'. (E) is incorrect because of absence of 'the' (definite article) to point out the noun (season).

Multiple choice

What is absolute zero?

  1. 00C

  2. 2730C

  3. � 2730C

  4. 1000C
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Absolute zero is the lowest limit of the thermodynamic temperature scale, a state at which the enthalpy and entropy of a cooled ideal gas reach their minimum value, taken as zero. This is -273.15 degrees Celsius.
