How mass is preserved in a growing plant and a rusting car

Conservation of Mass · 10:40 · Video: MIT OpenCourseWare · Watch at the source

In short: Discover how the law of conservation of mass applies to the natural world. This MIT OpenCourseWare video demonstrates how to use mass conservation and control volumes to track changes in everyday chemical processes.

The video explores the fundamental principle of mass conservation through practical examples of stoichiometry. By applying the concept of control volumes, students can calculate unknown variables in two distinct scenarios: the process of photosynthesis in a growing plant and the oxidation of iron in a rusting car.
