Temperature Concepts Questions

Multiple choice physics acoustics conditions for hearing echo echo reflection of sound and echo ultrasound and its applications

An echo is heard on a day when temperature is about $44^0$C. When will the echo be heard if the temperature falls to $80^0$C?

  1. Sooner

  2. Later

  3. At the same time

  4. No echo will be heard
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Time, after which an echo is heard is given by $t = \dfrac {Distance}{Speed \ \ of \ \ sound \ \ in \ \ air}$
Therefore, since speed of sound in air increases with the increase in temperature, so the time after which echo will be heard decreases. Hence, echo will be heard, sooner than the echo heard when temperature near $44^0C$

Multiple choice various types of barometer fluids physics

The brass scale of a barometer gives correct reading at $10^{ o }C$. The barometer reads 75 cm at $30^{ o }C$. What is the atmospheric pressure at $8^{ o }C$(in cm Hg)

  1. 74.8

  2. 75.03

  3. 70

  4. 60
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The apparent reading of the barometer changes due to the thermal expansion of both the mercury and the brass scale. By correcting for the volume expansion of mercury and the linear expansion of the brass scale, the true pressure at 30 degrees Celsius can be converted to find the pressure at the reference temperature, yielding 75.03 cm of Hg.

Explanation

The most common method of refining crude is the process of fractional distillation. This involves heating crude oil to about 350 degrees Celsius,to turn it into a mixture of gases. These are piped into a tall cylinder, known as a fractional tower. The higher the gas rises in the tower, the lower the temperature becomes. Petrol or gasoline, condenses out at around 110 degrees celsius, while petroleum gas is drawn off at the top. The distilled liquid from each level contains a mixture of alkanes, alkenes, and aromatic hydrocarbons with similar properties, and requires further refinement and processing to select specific molecules. A process called cracking is used to produce more of the lower molecular weight hydrocarbons from higher ones.

  1. -18 degree Celcius

  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$^0$

  2. $70^{o}C$
  3. $10^{o}C$
  4. $18^{c}ircC$

What is the highest range of temperature in the Sahara desert in Fahrenheit ?

  1. $125^0$
  2. $130^0$
  3. $135^0$
  4. $145^0$
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In addition to being extremely dry, the Sahara is also one of the hottest regions in the world. The average annual temperature for the desert is 86°F (30°C) but during the hottest months temperatures can exceed 122°F (50°C), with the highest temperature ever recorded at 136°F (58°C) in Aziziyah, Libya.

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".
