Answer :
Final answer:
A change of temperature equal to one Kelvin is equal to a change in temperature of 1 degree Celsius. They are equivalent in magnitude due to their identical unit size despite differing start points. The correct option is b.
Explanation:
A change of temperature equal to one Kelvin is equal to a change in temperature of 1 degree Celsius. Both the Kelvin and Celsius scales measure temperature, but they have different starting points. Kelvin begins at absolute zero, the coldest possible theoretical temperature, at which molecular motion ceases. The Celsius scale, however, begins at the freezing point of water.
Despite these differences in starting points, a 1-degree change in the Kelvin scale is equivalent to a 1-degree change in the Celsius scale. This equivalency exists because both scales are incremented in the same unit size; only their zero points differ. The correct answer to the question is therefore C) 1 degree Celsius.
