Question

convert -15°f to kelvins. round your answer to the correct number of significant figures. k

Explanation:

Step1: Convert Fahrenheit to Celsius

Use the formula $C=\frac{5}{9}(F - 32)$. Substitute $F=-15$ into the formula: $C=\frac{5}{9}(-15 - 32)=\frac{5}{9}(-47)\approx - 26.11^{\circ}C$.

Step2: Convert Celsius to Kelvin

Use the formula $K = C+273.15$. Substitute $C\approx - 26.11$ into the formula: $K=-26.11 + 273.15=247.04\approx247$ K.

Answer:

247
