  2. -15 degree Celcius

  3. -20 degree Celcius

  4. -10 degree Celcius
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Because Green House Gases are responsible to trap heat in earth surface. If green house gases are absent, the temperature of Earth shall fall down to -18 degree Celcius

So, the correct answer is '-18$^0$

At Shimla,the temperature was $-7^0C$ on Tuesday.It then dipped by $3^0C$ on Wednesday.On Thursday,it rose by $6^0C$.What was the temperature of Shimla on Wednesday and Thursday respectively?

  1. $-4^0C,-10^0C$
  2. $-10^0C,-4^0C$
  3. $-12^0C,-8^0C$
  4. $-10^0C,-40^0C$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
temperature on Tuesday is= $-7^{0}$
temperature on Wednesday is drop by $3^{0}C$ then temperature on Wednesday is equals to= $-7^{0}C-3^{0}C=-10^{0}C$
Now on Thursday temp. raise by $6^{0}C$ then temp. on Thursday is=$-10^{0}C+6^{0}C=-4^{0}C$ 
hence option $B$ is correct.

Multiple choice physics heat and energy causes of greenhouse effect global warming adaptation in animals

Without green house effect, the average temperature of earths surface would have been :

  1. $-18^{\circ}C$
  2. $33^{\circ}C$
  3. $0^{\circ}C$
  4. $15^{\circ}C$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

If an ideal thermally conductive black body were the same distance from the Sun as the Earth is, it would have a temperature of about 5.3 C. However, since the Earth reflects about 30% of the incoming sunlight, this idealized planet's effective temperature (the temperature of a black body that would emit the same amount of radiation) would be about 18 C. The surface temperature of this hypothetical planet is 33 C below Earth's actual surface temperature of approximately 14 C. The mechanism that produces this difference between the actual surface temperature and the effective temperature is due to the atmosphere and is known as the greenhouse effect.
Thus Option A is correct.

Temperature of the scrotum which is necessary for the functioning of testis is always around __________ below body temperature.

  1. $2^oC$
  2. $4^oC$
  3. $6^oC$
  4. $8^oC$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Scrotal temperature is about 2$^oC$' lower than the rest of the body. This temperature required for the process of sperm development, or spermatogenesis, (the process by which haploid spermatozoa develop from germ cells in the seminiferous tubules of the testis.) to proceed normally. 
So, the correct answer is '2$^oC$'. 
Multiple choice geography the realms of the earth atmosphere and its structures what is around us? the atmosphere the earth's structure

In the troposphere, the temperature decreases at the rate of $1^\circ$ Celsius for every _______.

  1. 100 meters

  2. 135 meters

  3. 150 meters

  4. 165 meters
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

$165 meters$

Higher up in the troposphere, where less heat from the surface warms the air, the temperature drops. Typically, the temperature drops about 6.5° C with each increase in altitude of 1 kilometer (about 3.6° F per 1,000 feet). The rate at which the temperature changes with altitude is called the "lapse rate".

  1. Thermophilic sulphur bacteria

  2. hot spring blue green agae

  3. methanogenic archaebacteria

  4. Marine archaebacteria
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Thermophilic sulphur bacteria can survive at high temperatures between 41 and 122$^o$C and an optimum growth temperature which is higher than 75$^o$C. Hot spring blue-green algae have an optimum growth temperature of 45$^o$C. Methanogenic archaebacterium grows at an optimum temperature of 35-40$^o$C. Some marine archaebacteria are extreme thermophiles and grow at temperatures of 65- 80$^o$C. 

So, the correct answer is 'Thermophilic sulpher bacteria'.
