On the Celsius scale, what are the ice point and steam point values?

The correct values for the ice point and steam point on the Celsius scale are indeed 0 degrees and 100 degrees, respectively. The ice point refers to the temperature at which water freezes, and this is defined as 0 degrees Celsius. On the other hand, the steam point is the temperature at which water boils and transitions to steam, which is defined as 100 degrees Celsius. These two points serve as critical reference markers in the Celsius temperature scale, establishing a clear relationship between the state changes of water and the temperature scale commonly used in science and daily life.

In contrast, the other choices reflect temperature points that are either aligned with the Fahrenheit scale or incorrect regarding the Celsius scale context. For example, 32 and 212 degrees correspond to the freezing and boiling points of water on the Fahrenheit scale, respectively, which does not apply in this case. Similarly, options that include 100 degrees without 0 degrees, or interchange 32 degrees with 0 degrees, do not represent the standard values recognized in the Celsius temperature scale.
