Question

convert 54°f to kelvins. round your answer to the correct number of significant figures. k

Explanation:

Step1: Convert Fahrenheit to Celsius

The formula to convert Fahrenheit ($F$) to Celsius ($C$) is $C=\frac{5}{9}(F - 32)$. Given $F = 54$, then $C=\frac{5}{9}(54 - 32)=\frac{5}{9}\times22=\frac{110}{9}\approx12.22^{\circ}C$.

Step2: Convert Celsius to Kelvin

The formula to convert Celsius to Kelvin ($K$) is $K=C + 273.15$. Substituting $C=\frac{110}{9}\approx12.22$ into the formula, we get $K=\frac{110}{9}+273.15\approx12.22+273.15 = 285.37\approx285$ K (rounded to 3 significant - figures as 54°F has 2 significant - figures and the operations in the conversion process should follow the rules of significant - figures).

Answer:

285
