convert 589 kelvin to °c
answer

Explanation:

Step1: Celsius to Kelvin formula

$K = ^\circ\text{C} + 273$

Step2: Convert 30°C to K

$30 + 273 = 303$

Step3: Convert -21°C to K

$-21 + 273 = 252$

Step4: Kelvin to Celsius formula

$^\circ\text{C} = K - 273$

Step5: Convert 589 K to °C

$589 - 273 = 316$

Answer:

303
252
316
