Sublimation:
- Sublimation can be defined as the transition from solid state to ‘gaseous state’ without going through the ‘liquid state’.
- This type of transition occurs only when the pressure and the temperature is below the ‘triple point’.
- This term represents only the changes of the phase physically and not through some random chemical reactions.
- For example, the paraffin wax vaporizes as gas is not considered as sublimation.
- When the dry ice changes into ‘vapour at room temperature’ and pressure is an example of sublimation.
