SUBIMATION PROCESS
Sublimation is the process in which a substance changes directly from a solid to a gas without passing through the liquid state. This unique phase transition occurs when the substance's vapor pressure exceeds its triple point pressure. Sublimation is the opposite of deposition, where a gas changes directly to a solid without passing through the liquid state.

EXAMPLES OF SUBLIMATION
Sublimation is a common phenomenon that can be observed in our daily lives. Some examples include the sublimation of dry ice (solid carbon dioxide) at room temperature, the sublimation of camphor, and the sublimation of naphthalene balls. These substances undergo sublimation when exposed to specific conditions, such as low pressure or increased temperature.

APPLICATIONS OF SUBLIMATION
Sublimation has various practical applications in different fields. In the field of chemistry, sublimation is used for purifying substances, such as separating mixtures of solids based on their sublimation properties. In the textile industry, sublimation is used for printing designs on fabrics using sublimation inks. Sublimation is also utilized in freeze-drying processes to remove moisture from food and pharmaceutical products without damaging their structure.
In conclusion, sublimation is a fascinating process that allows a substance to transition directly from a solid to a gas phase. Understanding the principles of sublimation has led to its application in various industries and research fields.
