Two metals are melted and mixed together. The resulting mass is cooled to solidify. What is this solid called ?

Options

A. An alloy
B. A non-metal
C. An oxide
D. A mineral

Explanation

To solve the question, "Two metals are melted and mixed together. The resulting mass is cooled to solidify. What is this solid called?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Process**: When two metals are melted, they are heated until they reach a liquid state. This process allows the metals to mix thoroughly.

**Hint**: Think about what happens when you heat metals together.

2. **Mixing the Metals**: Once the metals are melted, they are combined. This mixture can involve two or more metals or a combination of metals and non-metals.

**Hint**: Consider what happens when you combine different substances in a liquid form.

3. **Cooling the Mixture**: After mixing, the molten mixture is allowed to cool down. As it cools, it transitions from a liquid to a solid state.

**Hint**: Remember the process of cooling and how it affects the state of matter.

4. **Identifying the Resulting Solid**: The solid that forms after cooling is not just a simple mixture; it has specific properties and characteristics due to the combination of the metals.

**Hint**: Think about what we call a solid formed from a mixture of metals.

5. **Conclusion**: The resulting solid from the melting and mixing of metals is called an **alloy**. Alloys are homogeneous mixtures of two or more metals or a metal and a non-metal.

**Hint**: Recall the definition of an alloy and examples of common alloys.

### Final Answer:
The solid formed by melting and mixing two metals, which is then cooled to solidify, is called an **alloy**.
