Question

Which of the follwing is the smallest rise in temperature?

• A. $1^{\circ }F$
• B. $1K$
• C. $1^{\circ }C$
• D. All are of equal value

Answer 1

The correct option is A $1^{\circ }F$

There are 180 divisions in the Fahrenheit scale between the ice point and steam point while there are only 100 divisions in a Celsius scale.

And one scale division of a Kelvin scale is same as that of a Celsius scale.

So, $1^{0}F$ indicates a smaller rise in temperature than $1^{0}C$ and $1K$.
