What is the ideal temperature for the growth of bajra?

  1. $10^0C-15^0C$
  2. $15^0C-20^0C$
  3. $20^0C-25^0C$
  4. $25^0C-30^0C$
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

 Bajra is a crop of dry and warm climate and is grown in areas of 40-50 cm of annual rainfall. It seldom grows in those areas where the annual rainfall exceeds 100 cm. The ideal temperature for its growth is 25°-30°C. Bright sunshine after light showers is very useful in early stages of its growth.

Multiple choice social science water a precious resource water harvesting water resources and conservation water management

Assuming that the night will remain clear, calm, and unsaturated, the predicted minimum temperature is $32^{o}F$. Suddenly the wind speed increases and remains gusty throughout the night. The minimum temperature will most likely be:

  1. About the same as predicted but will occur earlier in the night

  2. Higher than predicted due to the release of latent heat

  3. Much lower than predicted due to radiational cooling

  4. Higher than predicted due to mixing
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Wind increases mechanical mixing of the air near the surface. This process brings warmer air from slightly higher altitudes down to the surface, preventing the temperature from dropping as low as it would under calm, clear conditions.

Multiple choice thermo flask thermos flask heat energy transfers transfer of heat physics

Liquid nitrogen is stored at $77K$ in a vacuum flask. The surrounding atmospheric temperature in the lab is $33K$.

  1. After a few days, the temperature of liquid nitrogen will increase.

  2. After a few days, the temperature of the lab will decrease.

  3. After a few days, the temperature of liquid nitrogen will decrease

  4. After a few days, the temperature of liquid nitrogen will remain unchanged.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Liquid nitrogen is stored at $77K$ in vacuum flask. The surrounding atmosphere temperature of the lab is $33K$.
After a few days, the temperature of liquid nitrogen will remain unchanged. Because, vacuum flask is designed to prevent heat loss by conduction, convection and radiation. So, the temperature remains unchanged.
Multiple choice temperature control homeostasis coordination and response biology

The normal temperature of human body on the Kelvin scale is

  1. 280

  2. 290

  3. 300

  4. 310
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Normal body temperature is 37 degree Celsius. To convert from Celsius to Kelvin add 273. So 37 + 273 = 310 degrees Kelvin.

Therefore, the correct answer is option D.

Human temperature is set at

  1. $47.5^0$C
  2. $37^0$C
  3. $37^0$F
  4. $98.4^0$C
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • In humans, the average internal temperature is 37.0 °C (98.6 °F).
  • Hypothermia is a medical emergency that occurs when your body loses heat faster than it can produce heat, causing a dangerously low body temperature.
  • Hypothermia occurs as your body temperature falls below 35.0 °C.
  • Hence Human temperature is set at 37.0 °C.
  • So, the correct answer is '37.0 °C'.

The normal temperature of human body on the Kelvin scale is ............ K

  1. 280

  2. 290

  3. 300

  4. 310
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Kelvin is the unit of measurement of temperature on an absolute scale. Kelvin temperature scale has an absolute zero below which temperatures do not exist. Absolute zero, is the temperature corresponds to a temperature of - 273.15° on the Celsius scale.The normal temperature of human body is 36.85$^0 $C.   

Temperature in kelvin = temperature in celsius + 273.15
Temperature in kelvin = 36.85 + 273.15 = 310 K.
Thus, the correct answer is option D.

The optimum temperature for respiration is 

  1. 20 -30$^o$C
  2. 25 -60$^o$C
  3. 40 -50$^o$C
  4. 10 -30$^o$C
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Respiration is the breakdown of the carbon-carbon bond to release energy.

This process is done with the help of a variety of different enzyme and as we know that the enzyme works efficiently in a narrow range of temperature.
The optimum temperature range for respiration is 20- 30-degree Celsius in which the enzyme work efficiently and the respiration is carried out.
So, the correct option is ' 20-30°C'
