If the initial temperature of the sample is 64.0 ∘F, what is its temperature in degrees Fahrenheit when the desired temperature increase has been achieved?

Answer:136 degree F

Explanation:

From the formula

(C - 0) / 100 = (F - 32) / 180

C / 100 = (64 - 32) / 180

C=17.78 Degree C

Temperature raised by 40 degree C

Total C = 40 + 17.78 = 57.78

Convert 57.78 to degree F

57.78/100 = F-32 / 180

F = 57.78*1.8 + 32

Ans = 136 degree F
