Question

Which three temperature readings all mean the same thing?

A). 100 Kelvin, 0 degrees Celsius, 32 degrees Fahrenheit


B). 273 Kelvin, 0 degrees Celsius, 212 degrees Fahrenheit


C). 373 Kelvin, 100 degrees Celsius, 212 degrees Fahrenheit


D). 273 Kelvin, 100 degrees Celsius, 212 degrees Fahrenheit

Answer 1

C). 373 Kelvin, 100 degrees Celsius, 212 degrees Fahrenheit

Step-by-step explanation:

Answer 2

C). 373 Kelvin, 100 degrees Celsius, 212 degrees Fahrenheit

Step-by-step explanation:

Kelvin and Celsius are related using the equation K = C + 273.

Celsius and Fahrenheit are related using the equation F = (9/5) * C + 32.

This means that Kelvin and Celsius have to differ by 273, in which only B and C fit that description.

Then you can look at the Celsius and Fahrenheit readings from B and C and apply the equation F = (9/5) * C + 32. For B, you take 0 degrees Celsius and substitute it in for C to get F = (9/5) * 0 + 32, in which you get 32 degrees Fahrenheit and not the 212 degrees in answer B. For C, you do the same: F = (9/5) * 100 degrees Celsius + 32 = 212 degrees Fahrenheit, which does agree with the answer. Therefore, it must only be C.
