States of Matter Concepts

The video explains the three states of matter: solids, liquids, and gases. It describes how particles are arranged in each state and their properties. Solids have fixed shapes, while liquids and gases take the shape of their containers. The video includes a demonstration of these properties and discusses how temperature changes can alter the state of matter, such as melting, boiling, and sublimation. It concludes with information on additional resources.

What are the three states of matter that can be observed by boiling water in a kettle?
