Correct:
A
Explanation
To convert a temperature from the Fahrenheit scale to the Kelvin scale, one must first convert Fahrenheit to Celsius or use a direct formula. The standard conversion formula is K = (F − 32)!5/9 + 273.15. Given the temperature is 113!F, the calculation begins by subtracting 32 from 113, resulting in 81. Multiplying 81 by 5/9 yields 45!C. Finally, adding 273.15 to the Celsius value gives approximately 318.15 K. Alternatively, using the direct formula K = (F + 459.67)!5/9 also results in 318.15 K. Rounding to the nearest whole number as per the options provided, 113!F corresponds to 318 K. This conversion is essential in scientific contexts where Kelvin is the absolute temperature scale.
