Question

The temperature of a body on Kelvin scale is found to be x K. When it is measured by a Fahrenheit thermometer, it is found to be xŗF. Then x is :

• A. 301.25
• B. 574.25
• C. 313
• D. 40

Answer 1

Answer: (B)

574.25

Answer 2

$\frac{x - 273}{373 - 273}$ = $\frac{f - 32}{212 - 32}$

Ž x – 273 = $\frac{5}{9}$ (x – 32)

Ž 9x – 9 × 273 = 5x – 160 Ž x = 574.25
