a change of 1 °f
i have never heard of a thomson degree. i presume it is the same as 1 k, because the british physicist william thomson is better known as lord kelvin, who invented the kelvin scale.
although the kelvin and celsius scales have different definitions, 1 k is the size as 1 °c.
on the celsius scale, the difference between the boiling point and freezing point of water is divided into 100 °.
on the fahrenheit scale, the same difference is divided into 180 °.
thus, a fahrenheit degree represents the smallest temperature change.
ur answer would be b hope i let me know if it is right
the answer to this questoin
