Multiple choice physics heat - measurement thermometers application of various thermometric scales different types of thermometers

When a mercury thermometer is inserted in a pot of hot water and the reading is recorded , what temperature is being 

  1. Average temperature of water and surroundings

  2. Average temperature of thermometer

  3. Average temperature of water and thermometer

  4. Temperature difference between water and surroundings
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In this process, thermal equilibrium will eventually be reached after inserting the thermometer in hot pot. Hence heat is transferred from the water to the thermometer. 

Multiple choice physics the kinetic model of matter force and kinetic theory change of states phase change

Normallly the body temperature of healthy person is ______ Degree celcius?

  1. 25

  2. 37

  3. 30

  4. 32
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Normally the body temperature of healthy person is $37^oC$ or ($98.6^oF$)
It is scientific fact that normal body temperature of a healthy body is $37^oC$. Apparently it is the perfect balance as it's warm enough to prevent fungal infection but not so hot that we need to eat non-stop to maintain out metabolism.

Explanation

Both a and b

Temperature is an objective comparative measurement of hot or cold. It is measured by a thermometer. Several scales and units exist for measuring temperature, the most common being Celsius (denoted $^{\circ}C$ and formerly called centigrade), Fahrenheit (denoted $^{\circ}F$).

  2. $0$

  3. Can't determine

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

A continuous variable can take any value within a given range, including decimals. Temperature can be measured to arbitrary precision, making it a continuous variable.

Multiple choice biology animals in daily life introduction to reproduction poultry farming food from animals

Eggs of chicken are incubated at _____________.

  1. $ 10^o C $
  2. $ 24^o C $
  3. $ 37^o C $
  4. $ 45^o C $
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Egg to chick in 3 weeks and require a constant temperature of $ 37.5^{\circ}C. $ Eggs will start to produce their own heat in the latter stages of development but the incubator thermostat takes care of this, keeping the temperature the same throughout the incubation period. It is same as human body temperature & the incubator maintenance the atmospheric carbon dioxide & nitrogen levels necessary to promote cell growth.
Multiple choice biology animals in daily life introduction to reproduction poultry farming food from animals

Eggs of chicken are incubated at

  1. 32$^o$C
  2. 45$^o$C
  3. 27$^o$C
  4. 38.9$^o$C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Poultry farming is the method of rearing and maintaining poultry birds. In poultry farm, there is two type of birds called as broilers and layers. Layers are the egg laying birds with low meat content. Broilers are the birds reared for the meat. For the development of chicken, layers incubate their eggs at a specific temperature. The recommended temperature is 102$^o$ Fahrenheit (38.9$^o$C). 

Multiple choice biology transport in plant transport of water and minerals conduction of water and minerals absorption of water and minerals in plants

Suitable temperature for active absorption of water by root is

  1. $40\, -\, 45^{\circ} C$
  2. $10\, -\, 15^{\circ} C$
  3. $20\, -\, 35^{\circ} C$

  4. Can take at any temperature
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Active absorption requires input of energy, which is obtained from cellular respiration. Respiration is an enzymatic process and is inhibited at extreme temperatures. Hence, the optimum temperature for active absorption is twenty to thirty five degree celsius.

Multiple choice biology transport in plant transport of water and minerals conduction of water and minerals absorption of water and minerals in plants

Optimum temperature for water absorption by plants is

  1. $ 0^o - 5^o C $
  2. $ 5^o - 20^o C $
  3. $ 25^o - 35^oC $
  4. $ 40^o - 50^o C $
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Temperature about 30°C favours water absorption. At higher tem­peratures water absorption is decreased. Also, low temperature decreases the permeability of the cell membrane. Metabolic activities of the root cells are decreased below the optimum temperature. 

So the correct answer is '25°C - 35°C'.

Multiple choice physics heat - measurement introduction to temperature application of various thermometric scales different types of thermometers

A new temperature scale uses X as a unit of temperature, where the numerical value of the temperature t$ _x$ in this scale is related to the absolute temperature T by t$ _x$ = 3T + 300. If the specific heat of a material using this unit is 1400 J kg$^{-1}$ X${^-1}$ its specificne in the S.I. system of units is

  1. 4200 J kg$^{-1}$ K$^{-1}$
  2. 1400 J kg$^{-1}$ K$^{-1}$
  3. 466.7 J kg$^{-1}$ K$^{-1}$

  4. impossible to determine from the information provided
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

$t _x = 3 T + 300                 Q = ms \Delta 0$
$\Delta t _x = 3 \Delta T$
$\displaystyle S = \frac{Q}{m \Delta \theta}                 S = \frac{Q}{m \Delta \theta}$
Since, unit of 8 is joule in both system
            X                                    T
$m = m _0 kg$                   $m _0 kg$
$Q = Q _0 J$                       $Q _0  J$
$\Delta t _x$                               $\Delta T$
$S _x = \displaystyle \frac{Q _0}{m _0 \Delta t _x} = 1400     S _r = \frac{Q _0}{m _0 \Delta T} = \frac{3 Q}{m _0 \Delta t _x}$
$S _r = 3 \times 1400 = 4200 J-kg^{-1} K^{-1}$

 The value of absolute zero temperature in Fahrenheit scale is 

  1. $ - 273^\circ F$
  2. $ - 32^\circ F$
  3. $ - 460^\circ F$
  4. $ - 132^\circ F$
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Absolute temperature in Celsius is $-273.15{{\,}^{o}}C$

$ F=\dfrac{9}{5}C+32 $

$ F=\dfrac{9}{5}\times (-273.15)+32=-459.67{{\,}^{o}}F $

$ F\cong -460{{\,}^{o}}F $

Hence, absolute temperature in Fahrenheit
