Question

If temperature scale is changed from C to F, numerical value of specific heat will
a)increase
b)decrease
c)remain same
d)nothing can be decided

Answer 1

Heya!!

Since magnitude of 1°F is equal to 5/9 of magnitude of 1℃, the numerical value of specific heat will decrease.

So, (B)Decrease is the correct answer

Hope it helps✌️✌️

Answer 2

Answer:

If the temperature scale is changed from C to F, the numerical value of specific heat will decrease i.e.option(b).

Explanation:

The relation between the Centigrade(°C) and Fahrenheit(F) scale is given as,

$F=32+\frac{9\times \textdegree C}{5}$       (1)

And the specific heat is given as,

$s=\frac{Q}{m\Delta T}$    (2)

Where,

s=specific heat

Q=heat supplied

m=mass of the substance

ΔT=change in temperature

• For scales that are linearly connected, a change in temperature indicates that specific would not be different.
• The Celsius and Fahrenheit scales, however, are linked by a ratio.

                      $\textdegree C\times \frac{9}{5}=F$      (3)

Thus the overall specific heat becomes $\frac{5}{9}$ times when Celcius is replaced with Fahrenheit. As a result, the specific heat value drops. i.e.option(b).
