Temperature Concepts Questions

Multiple choice

In hilly areas, water boils at a temperature of

  1. less than 100 degree Celsius

  2. more than 100 degree Celsius

  3. 100 degree Celsius

  4. 200 degree Celsius

  5. none of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

At higher altitudes, atmospheric pressure is lower. Since the boiling point of a liquid decreases as pressure decreases, water boils at a temperature below 100 degrees Celsius in hilly areas.

Multiple choice

Babies should be always kept in a reasonably warm temperature whereas adults can withstand extreme cold the reason for this is that

  1. They have a larger surface area of volume ratio hence they a large

  2. They have large volume to surface area ratio : hence they lose body heat greater than they produce

  3. a & b

  4. none
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Babies have a higher surface area to volume ratio compared to adults. This causes them to lose heat much faster to the environment, requiring them to be kept warmer.

Multiple choice

The normal temperature of the human body is

  1. 40 degree Fahrenheit

  2. 40 degree Celsius

  3. 100 degree Fahrenheit

  4. 37 degree Celsius
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The average normal human body temperature is approximately 37 degrees Celsius, which is equivalent to 98.6 degrees Fahrenheit.

Multiple choice

The temperature of a hot body, when measured by radiation pyrometer, is found to be 2450 deg. celsius assuming a surface emissivity of 0.85. Later on, it was found that the true surface emissivity is 0.78. Determine the actual temperature and error in temperature measurement.

  1. 2509 deg. celsius; - 59 deg. celsius

  2. 2509 deg. celsius; - 72 deg. celsius

  3. 3000 deg. celsius; - 60 deg. celsius

  4. 3490 deg. celsius; - 60 deg. celsius
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Actual Temperature = 2782 - 273 = 2509 deg. celsius Error in temperaure measurement = 2450 - 2509 = -59 deg. celsius

Multiple choice

The average temperature on Tuesday, Wednesday and Thursday was 340 and that for Wednesday, Thursday and Friday was 320. If on Friday the temperature was 350. Find what was the temperature on Tuesday.

  1. 41 degree

  2. 37.5 degree

  3. 38 degree

  4. 36 degree

  5. N/A
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Temperature on Tuesday+ Wednesday+ Thursday =3x 34 degree =102 degree Temperature on Wednesday+ Thursday+ Friday = 3x 32 degree = 96 degree Therefore difference between temperature on Tuesday &Friday = 102 degree - 96 degree = 6 degree  Temperature on Tuesday -35 degree =6 degree  Temperature on Tuesday =6 degree + 35 degree = 41 degree

Multiple choice

According to WHO, the bird flu virus cannot be transmitted through food cooked beyond

  1. 60°C

  2. 70°C

  3. 90°C

  4. 100°C

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

According to WHO, the bird flu virus cannot be transmitted through food cooked beyond 100°C. In areas experiencing outbreaks, poultry and poultry products can be safely consumed provided these items are properly cooked and properly handled during food preparation. The H5N1 virus is sensitive to heat. Normal temperatures used for cooking, i.e. 70°C in all parts of the food, will kill the virus.

Multiple choice

A boy was trying to read the thermometer by holding its bulb. His father told him that this method is incorrect and advised him not to hold the bulb of the thermometer while reading it. Why is it so?

  1. The bulb will break off easily.

  2. Mercury will come down to the bulb.

  3. It will give a wrong reading.

  4. The boy’s body temperature will increase by holding the bulb.

  5. The bulb may get dislogged.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

It will give a wrong reading as the temperature of the fingers will also affect the mercury.
