Question

The boiling point of turpentine on Fahrenheit scale is double its value on Celsius scale. If the boiling point of tar on Celsius scale is ${140}^{\circ }$ more than that of turpentine on same scale, find the boiling point of tar on Kelvin scale.

Answer 1

We know that $9C=5(F-32)$

Let the temperature in Celsius scale be T and in Fahrenheit be 2T.

So $9T=5(2T-32)$

$T={160}^{o}C$

Now the boiling temperature of turpentine $T_1=160+140={300}^{0}C$

We know for kelvin, $K=273+C=273+300$

In Kelvin scale it is $573K$.
