One Kelvin is the same size as one degree Celsius. true false

Step 1 ：The Kelvin and Celsius scales are indeed different, but the size of one degree in each scale is the same. The difference lies in the zero point of each scale. In the Celsius scale, 0 degrees is the freezing point of water, while in the Kelvin scale, 0 K is absolute zero, the lowest possible temperature. Therefore, the statement "One Kelvin is the same size as one degree Celsius" is true.

Step 2 ：Final Answer: The statement "One Kelvin is the same size as one degree Celsius" is \(\boxed{true}\).
