Question

Rank these temperatures from warmest to coldest.

A) 120 °F, 45 °C, 326 K
B) 326 K, 120 °F, 45 °C
C) 45 °C, 326 K, 120 °F
D) 326 K, 45 °C, 120 °F

Answer 1

To rank these temperatures from warmest to coldest, we convert them all to Kelvin and arrange them in that order.

Step-by-step explanation:

To rank these temperatures from warmest to coldest, we need to convert all the temperatures to a common scale. The Kelvin scale is the absolute temperature scale, so let's convert all the temperatures to Kelvin:

• A) 120 °F: To convert from Fahrenheit to Kelvin, we use the equation K = (°F + 459.67) x (5/9). So, K = (120 + 459.67) x (5/9) = 322.04 K.
• B) 326 K
• C) 45 °C: To convert from Celsius to Kelvin, we add 273.15. So, K = 45 + 273.15 = 318.15 K.

Now, let's arrange the temperatures from warmest to coldest: B) 326 K, A) 322.04 K, C) 318.15 K.
