  2. -10$^o$C, -4$^o$C
  3. 20$^o$C, -10$^o$C
  4. 25$^o$C, -100$^o$C
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The temperature of the surface waters varies mainly with latitude. The polar seas (high latitude) can be as cold as -2 degrees Celsius (28.4 degrees Fahrenheit), while the Persian Gulf (low latitude) can be as warm as 36 degrees Celsius (96.8 degrees Fahrenheit).
Temperature varies in ponds and lakes seasonally. During the summer, the temperature can range from $4^0$C near the bottom to $22^0$C at the top. During the winter, the temperature at the bottom can be $4^0$C, while the top is $0^0$C (ice).

Thus, the correct answer is option A.

  1. $6000^o C$
  2. $1000^o C$
  3. $10,000^o C$
  4. $9000^o C$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The photosphere, which is the visible surface of the sun, has an effective temperature of approximately 5778 Kelvin, which is commonly rounded to 6000 degrees Celsius.

Multiple choice vernalisation plant growth growth and development plant growth and development biology

Apple requires a low temperature for flowering and fruiting

  1. 10$^o$ C
  2. 7$^o$ C
  3. Below 7$^o$ C
  4. 10$^o$ - 15$^o$ C
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Apple grows in low temperature for germination it needs more time as earlier stages are less tolerant to low temperature but flowering starts at the temperature which is around 7 degree or below it that means it needs extreme cold climate to grow.

So the correct option is 'Below $7^o$ C'.

Multiple choice development of plants plant growth growth and development plant growth and development biology

Temperature range for plant growth is

  1. ${25}^{o} - {35}^{o}$
  2. ${0}^{o} - {35}^{o}$
  3. ${10}^{o} - {50}^{o}$
  4. ${0}^{o} - {20}^{o}$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Rate of plant growth and development depend upon various factors including temperature surrounding the plant. Each plant has a specific temperature range for optimum growth. The temperature affects plant growth processes such as photosynthesis, respiration, transpiration, protein synthesis, etc. In general, temperature range for plant growth is 0$^o$C to 35$^o$C. However, optimal day and night temperature range varies for plant growth.

Thus, the correct answer is option B.

Multiple choice physics pressure in liquids and gases common consequences of the atmospheric pressure atmospheric pressure and its consequences important points about atmospheric pressure

The height of a barometer at a temperature of $30^{o}$ appears to be $76\ cm$ according to the brass scale which gives correct reading at $0^{o}C$. $(\alpha _{Brass}=19\times 10^{-6}/ , \gamma _{Hg}=180\times 10^{-6}/ )$ 

  1. $74.22\ cm$
  2. $77.44\ cm$
  3. $78.49\ cm$
  4. $79.94\ cm$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The apparent height of the mercury column is affected by the thermal expansion of both the mercury and the brass scale. Using the formula for corrected height H = H_obs * (1 + gamma*deltaT) / (1 + alpha*deltaT), where gamma is the expansion of mercury and alpha is the expansion of brass, the calculation yields approximately 74.22 cm.

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 $44^0C$

A Correct answer
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.
