Chemistry · Some Basic Concepts of Chemistry

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Negative temperature values are possible on the Celsius scale, but temperatures below \( 0\text{ K} \) are not possible on the Kelvin scale. Reason (R): The Kelvin temperature scale has degrees identical in magnitude to the Fahrenheit scale. In the light of the above statements, choose the correct answer from the options given below:

1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
3. (A) is true but (R) is false.
4. (A) is false but (R) is true.
