Question

the boiling point of oxygen is 90 k. what is this temperature in degrees celsius?
°c = k - 273
-183 °c
273 °c
183 °c

Explanation:

Step1: Identify the conversion formula

The formula to convert Kelvin (K) to Celsius ($^{\circ}C$) is $^{\circ}C=K - 273$.

Step2: Substitute the given value

Given $K = 90$, substitute it into the formula: $^{\circ}C=90 - 273$.

Step3: Calculate the result

$90-273=- 183$.

Answer:

A. -183 $^{\circ}C$
