Question #2f2d6

Answer 1

The answer is (approximately) A) `261^@"F"`.

Explanation:

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

`T_(""^@"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.
