Explanation / Answer

a) the relation is

f = 9/5*c+32

if f = c

c = 9/5*c+32

c-9/5c = 32

c = -40

or f = 9/5f+32

f = -40

so at the cold temperature of negative 40 is the same on both the fahrenheit and celsius scales.

b) relation is

k-273.15 = 5/9(f-32)

if k = f

k-273.15 = 5/9(k-273.15)

k-5/9k = 273.15-5/9*273.15

k = 574.59 F

at 574.59 kelvin the fahrenheit temperature will be 574.59 F
