UPSC NDA-2 – 2019
Given T_F = 113 °F, T_C = (113 – 32) * 5/9 = 81 * 5/9 = 9 * 5 = 45 °C.
The formula for converting Celsius (T_C) to Kelvin (T_K) is T_K = T_C + 273.15. For practical purposes in MCQs, 273 is often used.
Using 273: T_K = 45 + 273 = 318 K.
Using 273.15: T_K = 45 + 273.15 = 318.15 K.
Since 318 K is an option and close to 318.15 K, it is the intended answer using the approximation of 273.
