Interpretation:
Solid: Solid is a sample of matter that retains its shape and density when not confined. Stronger forces of attraction exist between atom/ions/ molecules.
Liquid: A liquid is a sample of matter that conforms to shape of container in which acquires a defined surface in the presence of gravity. In this state weaker force exist between atoms/ ions/ molecules.
Gas: A gas is a sample of matter that conforms to the shape of container in which it is placed and acquires whole volume of container.
Negligible forces of attraction exist between atoms/ions/molecules.
Supercritical fluid: Fluid over its critical temperature and pressure exhibiting good solvent power.
Boling point: The boiling point of a substance is the temperature at which the vapour pressure of the liquid equal the pressure surrounding the liquid and liquid change in vapour
Normal point: The normal boiling point of a substance is defined as the temperature at which the vapour pressure of the liquid becomes equal to at the sea level.
Concept introduction:
This is the generic phase diagram. This graph show phase change as a function of temperature and pressure.
To determine:
