<p>What is the SI unit for mass, and how is it abbreviated?</p>

<p>Name two examples of materials that typically have a lustrous appearance.</p>

<p>Describe the difference between transparent and opaque materials, providing one example for each.</p>

<p>Identify the property of matter that quantifies the amount of substance present in an object.</p>

<p>Compare the properties of a rubber ball and a stone, specifically focusing on their hardness and bounce characteristics. Explain why they are used for different purposes.</p>

<p>You are asked to build a small boat that can float on water. Analyze which material properties would be most crucial for the boat&#39;s construction.</p>

<p>Explain how the properties of hardness and softness are determined for materials, and illustrate with an example why these properties are considered relative.</p>

<p>Compare and contrast the appearance of a freshly cut piece of aluminium foil with an old, tarnished copper coin. Identify the property that causes their difference in appearance.</p>

<p>You are given a mixture of sand and sugar. Apply your knowledge of solubility to describe a method to separate the sugar from the sand.</p>

<p>Contrast the behavior of mustard oil and vinegar when mixed with water. Explain the property responsible for their different behaviors.</p>

<p>Explain why a tumbler made of cloth cannot be used for storing water.</p>

<p>Describe what is meant by &#39;lustrous appearance&#39; in materials and name two metals that typically exhibit this property.</p>

<p>Explain the concept of classification as it applies to objects and materials.</p>

<p>List the three categories of materials based on how much light can pass through them, and briefly explain what each category means.</p>

<p>Apply the definition of matter to determine if water, air, and light are considered matter. Justify your answer for each.</p>

<p>A $250$ mL glass is filled completely with water. If you pour this water into a $1$ L bottle, calculate what fraction of the bottle&#39;s volume will be filled with water.</p>

<p>Summarize why different materials are chosen for making different objects, such as a cooking utensil versus a tumbler.</p>

<p>Identify and describe the two fundamental properties that all materials possess, which together define what &#39;matter&#39; is.</p>

<p>Analyze why a school bag is typically made from cloth or synthetic fabric instead of materials like glass or paper, considering the properties of materials.</p>

<p>A chef wants to store cooking oil, salt, and wheat flour in containers. Analyze why transparent containers are often preferred for these items in a kitchen.</p>

<p>Examine the materials used for making cooking utensils. Why are metals like steel or aluminium preferred over materials like plastic or wood for the main body of a cooking utensil?</p>

<p>If you have $1$ kg of cotton and $1$ kg of iron, analyze which material occupies more space and why, even though their masses are equal.</p>

<p>Summarize five of the 20 properties (guna) used in the ancient Indian medical system of Ayurveda to describe physical matter.</p>
