A) Diffusion
B) Evaporation
C) Condensation
D) Sublimation
- Sublimation is the process where a solid changes directly into a gas without becoming a liquid first.
- It happens under certain conditions of temperature and pressure, like dry ice turning into carbon dioxide gas.
- Sublimation is used in processes like freeze-drying food and in purifying some chemicals.
🧠 Explanation:
Sublimation is the process where a solid turns directly into a gas. Knowing this helps students and science enthusiasts understand phase changes. Sublimation is key for studying chemistry or physics in school. Learning this helps with science projects or exploring material properties. It’s useful for science classes, making it relevant for understanding states of matter. Knowing sublimation helps students grasp its mechanics, ensuring better comprehension for academic work or general knowledge about chemical processes.
