Question

Convert 40°C to the (a) Fahrenheit scale (b) Kelvin Scale.

Answer 1

(a) Fahrenheit scale
C = 40°C
Substitute value of C = 40° in below equation

`"C"/5 = ("F"-32)/9`

`40/5 = ("F"-32)/9`

     `8   =  ("F"-32)/9`

   8 × 9 = F - 32

      72  = F - 32

       F   = 72 + 32 = 104

Solution = 104 ° F 

(B) t° C = (273 + t ) K 

Given  t = 40° c 

Substitute the value of t in above equation 

40°C = (273 + 40) K 

40° C = 313 K 

Solution  = 313 k
