The correct Answer is:
To determine which properties alloys are generally prepared to modify, let's analyze each option step by step. ### Step 1: Understanding Alloys Alloys are defined as solid solutions made from two or more metals or a metal and nonmetal. They are created to enhance certain properties of the base metal. **Hint:** Remember that alloys can be made from combinations of metals and nonmetals. ### Step 2: Analyzing Malleability Malleability refers to the ability of a material to deform under compressive stress. Alloys can be designed to modify malleability. For example, gold and silver are often alloyed with other metals to decrease their malleability, making them more suitable for applications like jewelry and utensils. **Hint:** Consider how the addition of other metals can change the malleability of pure metals. ### Step 3: Analyzing Toughness Toughness is the ability of a material to absorb energy and plastically deform without fracturing. Alloys can be engineered to improve toughness. For instance, certain steel alloys are made to enhance toughness, making them more resistant to impact. **Hint:** Think about how toughness can be critical in applications where materials face stress and impact. ### Step 4: Analyzing Resistance to Corrosion Corrosion resistance is the ability of a material to withstand degradation due to chemical reactions with its environment. Alloys are frequently created to improve corrosion resistance. Stainless steel, for example, is an alloy that is specifically designed to resist corrosion. **Hint:** Reflect on how certain environments can affect metals and how alloys can be tailored to resist these effects. ### Conclusion Based on the analysis of all three properties: - Alloys can modify malleability (A). - Alloys can enhance toughness (B). - Alloys can improve resistance to corrosion (C). Thus, the correct answer is that all options (A, B, and C) are correct. **Final Answer:** All options are correct (A, B, and C).
