Question

The temperature of a body on Kelvin Scale is found to be x° K. When it is measured by Fahrenheit thermometers. It is found to be x° F, then the value of x is.

(A) 313

(A) 301.24

(C) 574.25

(D) 40

Answer 1

Correct option: (C) 574.25

Explanation:

[(F – 32) / 9] = [(K – 273) / 5]

∴ F – 32 = (9/5)(K – 273)

Given : Temperature on kelvin scale = xk

Temperature on Fahrenheit = xF

∴ F = K = x

∴ x – 32 = (9/5)(x – 273)

(4/5)x = 459.67

∴ x = 574.25
