(a)
Interpretation:
Behaviour of Iodine vapour when cooled at given pressures has to be described.
Concept introduction:
- Phase transition: Change of substance from one state to another state is known as phase transition or change of state.
Example: Freezing, melting, vaporization, sublimation and condensation.
- Phase diagram: Phase diagram is a graphical representation to review the conditions under which varies states of a substance is constant.
- Triple point: A point at which three phases of a substance meets together.
- Critical point: The critical point is end point of the phase equilibrium curve in phase diagram.
