<!-- wp:paragraph -->
<p>Hello students, and welcome back to <strong>Chemistry class</strong>!<br>In our previous lesson, we introduced the concept of <strong>Chemistry</strong> and explored its foundational principles. Today, we will be focusing on a very important topic: <strong>Properties and Classification of Matter</strong>.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>Get your writing materials ready as we dive into this fundamental concept in chemistry.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>Let’s get started with the questions and answers.</p>

<!-- wp:list -->
<ul class="wp-block-list"><!-- wp:list-item -->
<li>Define <strong>matter</strong></li>
<!-- /wp:list-item -->
<!-- wp:list-item -->

<h2 class="wp-block-heading" id="h-what-is-matter">What is Matter?</h2>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p><strong>Matter</strong> is anything that has <strong>mass</strong> and occupies <strong>space</strong>. This means everything you can see, touch, or feel around you is considered matter — including <strong>human beings, vehicles, chairs, tables, computers, and even air</strong>.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>In simpler terms, matter refers to anything that physically exists and takes up space in the universe.</p>

<!-- /wp:heading -->
<!-- wp:list -->
<ul class="wp-block-list"><!-- wp:list-item -->
<li><strong>Particle Arrangement:</strong><br>Particles in solids are <strong>tightly packed</strong> and usually arranged in a regular pattern.</li>

<li><strong>Properties of Solids:</strong><!-- wp:list -->
<ul class="wp-block-list"><!-- wp:list-item -->
<li>They <strong>retain their shape</strong> and do not take the shape of a container.</li>
<!-- /wp:list-item -->
<!-- wp:list-item -->

<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>Matter is the foundation of chemistry. Understanding its <strong>definition, properties, and classification</strong> helps students grasp more complex topics in science. From the <strong>solid, liquid, and gaseous states</strong> to differentiating between <strong>elements, mixtures, and compounds</strong>, this topic builds the base for future lessons in <strong>chemical reactions and physical changes</strong>.</p>
