Question

what is the temperature in kelvins of -14⁰c?

a. 259 k

b. -19.5 k

c. -287 k

d. -3822 k

Explanation:

Step1: Recall the formula to convert Celsius to Kelvin

The formula to convert temperature from Celsius (\(^\circ\text{C}\)) to Kelvin (K) is \(T(\text{K}) = T(^\circ\text{C}) + 273.15\).

Step2: Substitute the given Celsius temperature into the formula

We are given \(T(^\circ\text{C})=- 14^\circ\text{C}\). Substituting this into the formula: \(T(\text{K})=-14 + 273.15\).

Step3: Calculate the result

\(-14+273.15 = 259.15\approx259\) (when rounded to the nearest whole number).

Answer:

A. 259 K
