Concept explainers
Interpretation:
Among the given options, which one belongs to changes of state is the final state that of solid has to be chosen.
Concept Introduction:
A change of state is a cycle in that a substance is transformed from one physical state to another physical sate. The physical changes of a substance occurs by either heating or cooling. There are six possible changes of state and they are freezing, melting, evaporation, condensation, sublimation, and deposition. The below mentioned figure will represent each of the physical changes of a substance from starting stage to final stage via intermediate stage.

- Problems Imagine a substance with the following points on the phase diagram: a triple point at .5 atm and -5°C; a normal melting point at 20°C; a normal boiling point at 150°C; and a critical point at 5 atm and 1000°C. The solid- liquid line is "normal" (meaning positive sloping). For this, complete the following: 1. Roughly sketch the phase diagram, using units of atmosphere and Kelvin. 1-solid, 2-liquid, 3-gas, 4-supercritical fluid, point O-triple point, C-critical point -78.5 °C (The phase of dry ice changes from solid to gas at -78.5 °C) 2.
