How does sublimation work in forensic science?
There are practical applications of sublimation in forensic sciences. To purify the volatile compounds, the purification method in use by chemists is sublimation. One important use of sublimation is in the frozen food industry which is called freeze-drying. This sublimation from the solid phase to the gas phase of frozen water in the material takes place when we reduce surrounding pressure. No heat is involved during the removal of water hence it is different from evaporation. As there is the use of very low temperatures, a high-quality product is obtained. The structure of the product is also maintained and after rehydration, excellent quality is obtained. When the food product needs to be preserved for a long time, this technique comes into use. Such as when astronauts go out to outer space, space organizations such as NASA, ISRO provide quality food using this technique.
What is sublimation in science?
Answer: Sublimation includes freezing, melting, and evaporation. It is a shift in a state of matter. Without even undergoing the liquid phase, the substance transforms from a solid to a gas by sublimation. For example dry ice, heavy CO2. Q.2.
What is the energy of sublimation?
The energy which is calculated is the enthalpy of sublimation. Sublimation only occurs at pressures and temperatures below the triple point of a substance. The pressure and temperature at which the substance will exist in all three phases that is a solid phase, gaseous phase, and the liquid phase are the triple point of a substance.
Why is sublimation called an endothermic reaction?
When some molecules absorb heat energy, they are at a much higher energy state than their neighbours, hence overcoming the force of attraction and therefore escape into the vapour phase. It is called an endothermic reaction because of the additional energy required. Then sublimation is defined as heat or energy required to change the state from solid to gas. It is expressed as or even .

What Is Sublimation?
Otherwise known as all over print, sublimation printing is a design process where inks are transferred onto the product using heat.
How does sublimation work?
Sublimation printing uses heat to fuse ink and surface material or fabric, depending on the case. The inks used in the sublimation process turn into gas when brought under heat, then combine with the textile and permanently imprint onto the fabric. The result is permanent and significantly less prone to fading, as the ink penetrates the material instead of simply laying on top like a regular print.
What About Sublimation Shirt Printing?
When it comes to sublimation t-shirt printing, the artwork is first printed onto a special sheet of paper. That image is then transferred onto another material, like polyester or a polyester mix, and the ink then gets heated until it literally disintegrates into the material. The process of sublimation shirt printing may cost more than other methods (screen printing) but it lasts longer and won’t crack or peel over time. And did we mention it looks way cooler?
