Answer

225 K Explanation 1. Convert Fahrenheit to Celsius Use the formula: \( C = \frac{5}{9}(F - 32) \). For ( F = -55 ), calculate \( C = \frac{5}{9}(-55 - 32) = \frac{5}{9}(-87) = -48.33 \). 2. Convert Celsius to Kelvin Use the formula: ( K = C + 273.15 ). For ( C = -48.33 ), calculate ( K = -48.33 + 273.15 = 224.82 ).
