Question

Assertion (A): The absolute scale of temperature is the Kelvin scale.

Reason (R): Kelvin scale starts from 0°C.

विकल्प

• Both A and R are true and R is the correct explanation of A.

• Both A and R are true but R is not the correct explanation of A.

• A is true but R is false.

• A is false but R is true.

Answer 1

A is true but R is false.

Explanation:

The Kelvin scale is the absolute temperature scale, so A is true. It begins at absolute zero, 0 K (equal to −273°C), not at 0°C; therefore R is false.
