The correct option is A) 318 K.
To convert temperature from Fahrenheit to Kelvin, one must first convert from Fahrenheit to Celsius and then from Celsius to Kelvin.
The formula for converting Fahrenheit (T_F) to Celsius (T_C) is T_C = (T_F – 32) * 5/9.
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.
