Multiple choice physics measurement and effects of heat heat exchange calorimeter measuring thermal quantities by the method of mixtures

At which temperature do the readings of the celcius and the Fahrenheit scales coincide ?

  1. $0$
  2. $100$
  3. $-40$
  4. $-80$

  5. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

We know the relation between celsius and Fahrenheit is given by , 

$ ^0 C = \dfrac{9}{5}  \times ^0F + 32 $
For readings to coincide ,  $ ^0 C = ^0 F$
$ ^0 C = \dfrac{9}{5}  \times ^0C + 32 $
On Solving, $ ^0 C = -40 $

A steel tape is calibrated at $20 ^ { \circ } \mathrm { C }$. On a cold day when the temperature is $- 15 ^ { \circ } \mathrm { C }$ percentage error in the tape will be $\left[ \alpha _ { \text { steel } } = 1.2 \times 10 ^ { - 5 \cdot 0 } C ^ { - 1 } \right]$

  1. $0.035 \%$
  2. $0.042 \%$
  3. $0.012 \%$
  4. $0.018 \%$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The change in length due to temperature is delta L = L * alpha * delta T. The percentage error is (delta L / L) * 100 = alpha * delta T * 100. Here, alpha = 1.2 * 10^-5 and delta T = 20 - (-15) = 35. So, 1.2 * 10^-5 * 35 * 100 = 0.042%.

A faulty thermometer has its fixed point marked $5C$ and $95 C$. This thermometer reads the temperature of a body as $59^o$. The correct temperature on Celsius scale is 

  1. $64^{0}$
  2. $54^{0}$
  3. $60^{0}$
  4. $68^{0}$
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
For two scales of thermometer,

$\dfrac{C-0}{100-0}=\dfrac{Reading}{UPF-LPF}-LPF$

where, $LPF$ and $UPF$ are the lower and upper fixed points on the scale.

Therefore

$\dfrac{C}{100}=\dfrac{59-5}{95-5}=\dfrac{54}{90}=0.6$

$\implies C=0.6\times 100=60^0$
