Question

convert 11°f to kelvins. round your answer to the correct number of significant figures. \boxed{} k

Explanation:

Step1: Convert °F to °C

Use formula: $^\circ\text{C} = \frac{5}{9} \times (^\circ\text{F} - 32)$
$\frac{5}{9} \times (11 - 32) = \frac{5}{9} \times (-21) \approx -11.6667^\circ\text{C}$

Step2: Convert °C to Kelvin

Use formula: $\text{K} = ^\circ\text{C} + 273.15$
$-11.6667 + 273.15 = 261.4833$

Step3: Round to sig figs

11°F has 2 sig figs, so round result.
$261.4833 \approx 260$

Answer:

260 K
