Question

The specific heat of a substance is 0.09cal/gm*0C. if the temperature is measured in fahrenheit scale the value of its specifi heat in cal/gm*0F

Answer 1

Answer:

Given: The specific heat of a substance is 0.09 cal/gm°C

To find:  If the temperature is measured in Fahrenheit scale the value of its specific heat in cal/gm/°F ?

Solution:

Now we have given the specific heat of a substance is 0.09 cal/gm°C.

We know the formula:

                T(c) = 5/9 (T(f) - 32)

                9T(c)/5 = T(f) - 32

Now consider T(c) = 1 degree, then:

                T(f) - 32 = 9/5 = 1.8

So  if 0.09 cal/gm°C, then :

                0.09 / 1.8 = 0.05 cal/g/°F

Answer:

              So f the temperature is measured in Fahrenheit scale the value of its specific heat is 0.05 cal/gm/°F
