Question

With three temperature readings all mean the same thing?

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

B. 273 Kelvin, 100 degrees Celsius, 212 degrees Fahrenheit

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

D. 273 Kelvin, 0 degrees Celsius, 212 degrees Fahrenheit

Answer 1

Ans: C

Temperature can be expressed in terms of :

Kelvin (K), Celsius (C) or Fahrenheit (F)

The three units are interchangeable.

1) Kelvin(K) and Celsius(C)

K = 273 + C ----(1)

2) Celsius(C) and Fahrenheit(F)

F = (C*9/5) + 32 ---(2)

Option C is correct because:

From eq(1), when C = 100

K = 273 + 100 = 373

From eq(2), when C = 100

F = (100*9/5)+32 = 212

Answer 2

The answer is C) 373 Kelvin, 100 degrees Celsius, 212 degrees Fahrenheit. This is the boiling point of water.

Hope this helps! :)
