Question

A block of ice at  -10°C is slowly heated and converted to steam at 100°C. Which of the following curves represent the phenomenon qualitatively:

Answer 1

The correct option is (4).

\(-10^\circ C\,ice \xrightarrow[change]{Temp} 0^\circ\, C\, ice \xrightarrow [change]{Temp} 0^\circ\, water \xrightarrow[change]{Temp}100^\circ\, C\, water \xrightarrow{face\, change} 100^\circ\, stream\)

In this process, there are two phase change and two temperature change.
