Question

1. matching

freezing point of water:
32°
0°
273
(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: Match freezing point units

• $32^\circ$ = Fahrenheit
• $0^\circ$ = Celsius
• $273$ = Kelvin

Step2: Convert $25^\circ\text{C}$ to K

Use formula $K = ^\circ\text{C} + 273$
$K = 25 + 273 = 298$

Step3: Convert 300 K to $^\circ\text{C}$

Rearrange formula: $^\circ\text{C} = K - 273$
$^\circ\text{C} = 300 - 273 = 27$

Step4: Convert $-10^\circ\text{C}$ to K

Use formula $K = ^\circ\text{C} + 273$
$K = -10 + 273 = 263$

Answer:

Matching (Freezing point of water):

$32^\circ$: Fahrenheit
$0^\circ$: Celsius
273: Kelvin

Conversions:

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