Understanding Matter and Its Properties

The video tutorial introduces the concept of 'jirim', exploring its properties and differentiating between physical and chemical properties. It explains how jirim is present in both living and non-living things, and discusses examples of physical and chemical changes. The tutorial also covers methods to measure these properties, providing a comprehensive understanding of the subject.
