# Question 2f2d6

The answer is (approximately) A) ${261}^{\circ} \text{F}$.

#### Explanation:

The conversion factor for going from Kelvin to degrees Fahrenheit looks like this:

${T}_{\text{^@"F") = 9/5 * T_(""^@"K}} - 459.67$

So, in your case, a temperature of 400 K would correspond to

T_(""^@"F") = 9/5 * 400 - 459.67 = 260.33""^@"F"#

So I assume that option (A) is the closest to this value.
