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