Question

Which of the following is NOT a Absolute Temperature Scale?

• A. Celsius Scale
• B. Rankine Scale
• C. Kelvin Scale
• D. None of these

Answer 1

The correct option is A Celsius Scale

An absolute scale is that in which , measurement starts from a minimum or zero point and which progresses in only one direction. For temperature measurement , Kelvin (related to Celsius scale) and Rankine (related to Fahrenheit scale) scales are absolute temperature scales .As they starts from a point at which molecular motion ceases ,absolute zero point .

Celsius scale starts from the freezing point of water hence it is a relative scale , not an absolute temperature scale ..
