The coldest hour of the day is approximately ______.

  1. 5 a.m.

  2. 9 p.m.

  3. 3 a.m.

  4. 10 a.m.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

5 a.m.

The coldest time of day can shift considerably if we have fronts moving through, varying winds and cloud cover or precipitation starting and stopping during the night or morning. However, assuming we have a more tranquil pattern, as we frequently do, with fair skies and light winds late at night and early in the day, the lowest temperature usually occurs a little after sunrise, sometimes as much as a half hour to an hour later.

Ram want to drink tea, when it is at $50^0C$. He ordered tea which arrives at a temperature of $80^0C$.tea takes one minute to cool from $80^0Cto60^0C$. If room temperature is $30^0C$, how long he has to wait to drink the tea?

  1. Less than one minute

  2. Two more minutes

  3. Half a minute

  4. Nearly three minute
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Newton's Law of Cooling states dT/dt = -k(T - T_env). For the first interval (80 to 60), average T is 70, difference is 40. For the second interval (60 to 50), average T is 55, difference is 25. Since the temperature difference is smaller, the cooling rate is slower, requiring more time.

The temperature of a room heated by a heater is $20^o$C when outside temperature is $-20^o$C and it is $10^o$C when the outside temperature is $-40^o$C. The temperature of the heater is

  1. 80$^o$C
  2. 100$^o$C
  3. 40$^o$C
  4. 60$^o$C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

the temperature diffrence should be equal for equilibrium
$(t-20)=20-(-20)$;

so, $t-10=10-(-40)$
$t=60$

Multiple choice geography climatic regions the climate and natural resources of gujarat introduction to weather and climate elements of weather and climate : temperature

The range of temperature of Mathura in comparison of Kolkata is______.

  1. Extreme

  2. Moderate

  3. Cold

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

Mathura, located in the interior of the Indian subcontinent, experiences a continental climate with extreme temperature variations between summer and winter. Kolkata, being near the coast, has a more moderate, maritime-influenced climate.

Multiple choice conduction in metals and non-metals thermal energy transfers physics

The temperature of skin is $T _{skin} = 34^0C$ (somewhat less than the body temperature, $T _{body} = 37^0C$) and the ambient tempreature is $T _{room} = 24^0C$. The surface area of an adult is A $\simeq$ 1.85 $m^2$. Calculate the net heat loss of the person.

  1. 25 W

  2. 100 W

  3. 300 W

  4. 500 W
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Heat loss can be estimated using Newton's Law of Cooling or basic heat transfer principles. Given the temperature difference (34-24 = 10 degrees) and surface area, the power loss is roughly 25-100W depending on the heat transfer coefficient. 25W is a common textbook answer for this specific problem setup.

Multiple choice physics heat - measurement sources of heat introduction to heat measuring temperature

At what temperature is the Fahrenheit scale reading equal to twice of Celsius ?

  1. $ 40^0C $
  2. $ 160^0C $
  3. $ 80^0C $
  4. $ 100^0C $
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

We know the relation between Fahrenheit scale and degree celsius,


$\dfrac{C-0}{100}=\dfrac{F-32}{180}$

Given,

$F=2C$

Then,

$\dfrac{C}{100}=\dfrac{2C-32}{180}$

$\dfrac{C}{100}=\dfrac{C-16}{90}$

$\implies 9C=10C-160$

$\implies C=160^0C$

  2. $15.5^{o}C $ to $16.5^{o}C $
  3. $1^{o}C $ to $2^{o}C $
  4. $13.5^{o}C $ to $14.5^{o}C $
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

According to the International Committee of Pure Physics, calorie is the standard unit to measure heat. The quantity of heat required to raise 1 gram of water from $14.5^o C \ to \ 15.5^o C$ is defined as a calorie.

Multiple choice geography agriculture in india - ii : food crops wheat cultivation in india production of agricultural crops food crops in india

 The ideal temperature for the cultivation of wheat is ______________.

  1. $5^0C-10^0C$
  2. $15^0C-20^0C$
  3. $20^0C-30^0C$
  4. $25^0C-35^0C$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Wheat requires cool temperatures during its growing season in the range of about 14°c to 18°c. Rainfall of about 50 cms to 90 cms is most ideal. However, during harvesting season in the spring, wheat requires bright sunshine and slightly warmer temperatures. Uttar Pradesh is the largest wheat growing state in India closely followed by Punjab and Haryana.

What is diurnal range of temperature?

  1. Difference in the maximum and minimum temperature of a day

  2. Difference in the maximum and minimum temperature of a week

  3. Difference in the maximum and minimum temperature of a month

  4. Difference in the maximum and minimum temperature of a year
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The temperature recorded throughout the 24-hour period shows that there is a rhythmic rise and fall of temperature during a day. This phenomenon is called the daily cycle of temperature. The difference between the highest and lowest values of temperature recorded at a locality is referred to as the diurnal range or daily range of temperature.

Multiple choice geography world of diversities elements of weather and climate :rainfall and air pressure diversified world environmental regions (zones)

What is meant by annual range of temperature?

  1. Difference in the mean temperature of summer and winter

  2. Difference in the maximum and minimum temperature of a year

  3. Both A and B

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

Temperature is a relative term implying a degree of molecular activity or heat of a substance. Temperature is recorded every day the difference between the maximum and minimum temperature for 24 hrs is called the range of temperature and the difference in mean temperature which recorded in the summer and winter is known as annual range of temperature.
