Question

You work in a materials testing lab and your boss tells you to increase the temperature of a sample by 34.0 ∘C . The only thermometer you can find at your workbench reads in degrees Fahrenheit.

If the initial temperature of the sample is 70.6 ∘F, what is its temperature in degrees Fahrenheit when the desired temperature increase has been achieved?

Answer 1

relation between celsius and Fahrenheit

C = (F - 32)*(5/9)

F = 32 + 9C/5

Now we need increase temperature of material by 34.0 C,

Now initial temperature in Fahrenheit = 70.6 F, So

Initial temperature in Celsius will be:

C = (70.6 - 32)*(5/9) = 21.44 C

Now to increase temperature by 34.0 C, final temperature in Celsius will be:

C1 = C + 34.0 = 21.44 + 34.0 = 55.44 C

Now 55.44 C in Fahrenheit will be:

Final temperature = 32 + 9*55.44/5

Final temperature = 131.792 F = 131.8 F
