Multiple choice evs - i the earth and its living world introduction to the spheres of the earth origin of universe introduction to natural resources

In mesosphere, the temperature

  1. Rises from - $2^0$ to $15^0$ C
  2. Rises from - $2^0$ to $92^0$ C
  3. Decreases from - $2^0$ to - $15^0$ C
  4. Decreases from - $2^0$ to - $92^0$ C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Temperatures in the mesosphere decrease with altitude. Because there are few gas molecules in the mesosphere to absorb the Sun’s radiation, the heat source is the stratosphere below. The mesosphere is extremely cold, especially at its top, about -90 degree Celsius.  So the correct answer is ' it decreases from -2 to -92 degrees. '

Which one of the following temperatures is approximately equal to "room temperature ?"

  1. $0\ K$
  2. $293\ K$
  3. $100$ Degree Celsius
  4. $0$ Degree Celsius
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Room temperature is typically defined as approximately 20 to 25 degrees Celsius, which corresponds to roughly 293 to 298 Kelvin.

Our body temperature is maintained at :

  1. ${20 ^ 0C }$
  2. ${41 ^0 C}$
  3. ${37 ^0 C}$
  4. ${11^0 C}$
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Our body temperature is maintained at $37^\circ C$ or $98^\circ F$ on an average. Our body has thermo-regulation mechanism that keeps the body at optimum operating temperature. Water plays an important role in this mechanism.

To convert Kelvin scale to Celsius scale:

  1. add $273$ to Kelvin scale
  2. subtract $273$ from Kelvin scale
  3. multiply $273$ with Kelvin scale
  4. divide $273$ by Kelvin scale
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
$^0C=K-273$
To convert Kelvin to Celsius, subtract $273$ from kelvin scale.

Hence, option $B$ is the answer.

Which temperature is hottest?

  1. $17^oC$
  2. $58^o F$
  3. $290 K$
  4. $16^o C$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Relation between celsius kelvin and fahrenheit scale.
${ T } _{ C }=\frac { 5 }{ 9 } ({ T } _{ F }-32){ =T } _{ K }-273.15$

$17^0C=17^0C$
$58^0F=\frac {58-32} {1.8}=14.44^0C$
$290K={290-273.15}^0C=16.85^0C$

$16^0C=16^0C$

$17^0C$ is hotter.
Option A is correct.

298 K is approximately what temperature in degrees Celsius?

  1. $25^oC$
  2. $24^oC$
  3. $29^oC$
  4. $27^oC$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Zero on the Celsius scale $(0^0C)$ is now defined as the equivalent to $273.15K$, with a temperature difference of $1^0C$ equivalent to a difference of $1K$, meaning the unit size in each scale is the same.

$T _k=T _c+273.15$
$T _k=$Temperature in kelvin.

$T _c=$Temperature in celsius.
$T _c=298-273=25^0C$.Option A is correct.

$298 K$ is what temperature in Fahrenheit?

  1. $76.73F$
  2. $80F$
  3. $75F$
  4. $27F$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

${ T } _{ K }={ (T } _{ F }+459.67)\times \frac { 5 }{ 9 } \ \Rightarrow 298={ (T } _{ F }+459.67)\times \frac { 5 }{ 9 } \ \Rightarrow \frac { 298\times 9 }{ 5 } -459.67={ T } _{ F }\ \Rightarrow { T } _{ F }=536.4-459.67={ 76.73 }^{ 0 }F$

The centigrade $(^0 C)$ scale can be converted into Kelvin scale by the formula:

  1. Temperature in Kelvin + 273

  2. Temperature in Kelvin - 273

  3. Temperature in Fahrenheit + 273

  4. Temperature in Fahrenheit - 273
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The temperature T in Kelvin (K) is equal to the temperature T in degrees Celsius $\displaystyle \left( ^{ \circ  }{ C } \right) + 273$: 


$\displaystyle { T } _{ \left( k \right)  }={ T } _{ \left( ^{ \circ  }{ C } \right)  }+273.15$

Therefore, temperature in $\displaystyle ^{ \circ  }{ C }$ =  temperature in Kelvin +273.

Hence, option B is correct.
