Temperature Concepts Questions

Multiple choice

What is the average temperature in the desert?

  1. 19-22 0

  2. 35-45 0

  3. 20-25 0

  4. 50-100 0
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

During the hottest periods, average daytime temperatures in hot deserts typically range from 35 to 45 degrees Celsius. Temperatures can drop significantly at night due to the lack of moisture in the air to retain heat.

Multiple choice

The coldest temperature ever recorded on earth was negative ____________ degrees celsius.

  1. 30

  2. 150

  3. 60

  4. 90
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The lowest ground temperature ever directly recorded on Earth was minus 89.2 degrees Celsius (rounded to 90) at the Soviet Vostok Station in Antarctica on July 21, 1983. Satellite data has since suggested even lower temperatures near minus 93 degrees Celsius, making 90 the closest and most accurate option among the choices.

Multiple choice

In food safety, 5°C-63°C is otherwise known as...

  1. Body Temperature

  2. Hot Holding Temperature

  3. The Danger Zone

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

The temperature range between 5 degrees Celsius and 63 degrees Celsius is known as the 'danger zone' because it is the optimal range for pathogenic bacteria to multiply rapidly in food.

Multiple choice

How do we describe the temperature of matter?

  1. We use a thermometer.

  2. We use a graduated cylinder.

  3. We use a triple beam balance.

  4. We use microscope.

A Correct answer
Explanation

A thermometer is the instrument used to measure the thermal energy or temperature of matter.

Multiple choice

The temperature on Venus is about ____________.

  1. 50 degrees

  2. 100 degrees

  3. 212 degrees

  4. 840 degrees
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The surface temperature on Venus is consistently around 460-470 degrees Celsius, which is approximately 840-900 degrees Fahrenheit.

Multiple choice

At what temperature are Celsius and Fahrenheit equal?

  1. What? Not at any temperature!

  2. 13°C and 13°F

  3. -40 °C and -40 °F.

  4. 20°C and 20°F
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The formula to convert Celsius to Fahrenheit is F = (C * 9/5) + 32. Setting F = C and solving gives -40 = -40.

Multiple choice physics temperature and heat modes of heat transfer - conduction conduction heat and modes of heat transfer

In a steady state the temperature of the ends A and B of a 20 cm long rod AB is 100$^o$C and 0$^o$C. The temperature at the point c distant 9 cm from a is :

  1. $45^o$C
  2. $55^o$C
  3. $60^o$C
  4. $65^o$C
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Temperature increasing per unit length $=\cfrac{100-0}{20}=5^oC/cm$
Temperature at $9cm$ from $a \\ =100^oC-(5^oC/cm\times 9cm) \\ =55^oC$
Multiple choice physics temperature and heat modes of heat transfer - conduction conduction heat and modes of heat transfer

Two thermometers are used to record the temperature of a room. If the bulb of one is wrapped in wet hanky:

  1. The temperature recorded by both will be same.

  2. The temperature recorded by the wet-bulb thermometer will be greater than that recorded by the other.

  3. The temperature recorded by dry-bulb thermometer will be greater than that recorded by the other

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The thermometer whose bulb is wrapped by wet hanky; undergoes evaporation process; and we know that evaporation results in cooling, so the wet bulb, thermometer will record less temperature than that of dry bulb thermometer.

Multiple choice biology global environmental change causes of greenhouse effect greenhouse effect pollution and its effects

If there is no greenhouse effect, then the average temperature at surface of earth would have been 

  1. $ 15 $
  2. $ -18 $
  3. $ -6 $
  4. $ 10 $
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Greenhouse gases like $ { CO } _{ 2 }, { CH }{ 4 } $ and $ { CFC } _{ s } $ are essential for keeping the earth warm and hospitable. They prevent a substantial part of long wave radiations emitted by earth to escape into space, but these gases radiate a part of this energy back to the earth. This phenomenon is called greenhouse effect. Because of green house effect, the mean annual temperature of earth is $ 15. $ In its absence, it will fall to $ -18. $
So, the correct answer is '$ -18. $'
Multiple choice biology global environmental change causes of greenhouse effect greenhouse effect pollution and its effects

In the absence of greenhouse gases, the temperature of earth's surface will fall to

  1. $0^o$C
  2. $-5^o$C
  3. $-10^o$C
  4. $-20^o$C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Without the Greenhouse gases, the average temperature of earth would be 0$^{o}$ F or -20$^{o}$ C. The naturally present Greenhouse gases allow most of the incoming solar radiations to warm the earth surface and do not let the thermal radiations to escape into the space. However, anthropogenic contribution to the Greenhouse gases increase the level of solar radiations trapped and thus increase the overall temperature leading to global warming.

Hence, the correct answer is '-20$^{o}$ C'.
