Note: The app does not include PhET’s Java or Flash sims. In addition, although we are currently working on improving the accessibility of our sims, most of the sims included in this app do not include keyboard navigation or screen reader access. As accessible sims become available, they will be updated within the app. Proceeds from the app support the development of more HTML5 sims. On behalf of the PhET team and the students whose lives you have helped improve — Thank you!

Read full description

Understand the unique phase change where a solid turns directly into gas with this interactive learning app by EduTech Era. The Sublimation app explains the entire process using simple language, clean animations, and 3D particle visuals. Students can easily observe how heat affects solid particles and how sublimation differs from melting or evaporation. With zoom, zoom-out, and rotation features, the app lets you explore particle behavior closely. Real-world examples like camphor, dry ice, and naphthalene help connect textbook concepts to daily life. Designed for school students, teachers, and self-learners, the app ensures clear understanding through visual learning. The app works fully offline, making it ideal for classrooms, tuitions, and home study. Perfect for science chapters on states of matter and changing states for Classes 6–8.
