Question

perform the following conversions: part 1 of 2 convert 121. °c to k. be sure your answer has the correct number of significant figures.

Explanation:

Step1: Recall temperature - conversion formula

The formula to convert Celsius to Kelvin is $K = ^{\circ}C+ 273.15$.

Step2: Substitute the given value

Substitute $^{\circ}C = 121$ into the formula: $K=121 + 273.15$.

Step3: Calculate the result

$121+273.15 = 394.15$. Since 121 has 3 significant - figures, the result should also have 3 significant - figures. Rounding 394.15 to 3 significant - figures gives 394 K.

Answer:

394 K
