Current Question (ID: 10722)

Question:
$\text{The temperature of a body on the Kelvin scale is found to be } x^{\circ} \text{K. When it is measured by a Fahrenheit thermometer, it is found to be } x^{\circ} \text{F, then the value of } x \text{ is:}$
Options:
  • 1. $40$
  • 2. $313$
  • 3. $574.25$ (Correct)
  • 4. $301.25$
Solution:
$\text{Using temperature-conversion formula:}$ $\Rightarrow \frac{C-0^{\circ}}{100-0^{\circ}} = \frac{F-32}{180}$ $\Rightarrow \frac{x-273}{100} = \frac{x-32}{180}$ $\Rightarrow 9x = 5x + 160 + 2457$ $\Rightarrow x = 574.25$
