Question

The temperature at which fahrenheit and kelvin scale give the same reading is _______

Answer 1

We know that for kelvin scale $K=C+273$ or $C=K-273$ ...(1)

Now we know $C=\frac{5(F-32)}{9}$

Putting the value from equation 1

Also $K-273=\frac{5(F-32)}{9}$

Let say $F=K=T$

$T-273=\frac{5(T-32)}{9}$

$T=574.25K$
