Question

(celsius / kelvin / fahrenheit)
conversions
use:
$k = ^\circ c + 273$
21)convert $25^\circ c \to k$
22)convert $300 k \to ^\circ c$
23)convert $-10^\circ c \to k$

Explanation:

Step1: Substitute °C into formula

$K = 25 + 273$

Step2: Calculate the sum

$K = 298$

Step1: Rearrange formula for °C

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

Step2: Substitute K into formula

$^\circ\text{C} = 300 - 273$

Step3: Calculate the difference

$^\circ\text{C} = 27$

Step1: Substitute °C into formula

$K = -10 + 273$

Step2: Calculate the sum

$K = 263$

Answer:

1. $298\ \text{K}$
2. $27^\circ\text{C}$
3. $263\ \text{K}$
