The correct Answer is:
To solve the question regarding the behavior of a hole in a copper plate when heated, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Thermal Expansion**: When a material is heated, its particles gain energy and move more vigorously, leading to an increase in the distance between them. This phenomenon is known as thermal expansion. 2. **Identifying the Material**: The question specifies that the plate is made of copper, which is a metal. Metals generally expand uniformly when heated. 3. **Considering the Hole**: The hole in the copper plate is surrounded by the metal. When the plate is heated, the entire plate expands, including the material around the hole. 4. **Effect on the Hole's Diameter**: As the surrounding metal expands outward, the hole itself will also expand. This is because the material around the hole pushes outward as it heats up, leading to an increase in the diameter of the hole. 5. **Conclusion**: Since the hole is part of the expanding material, the diameter of the hole will increase when the copper plate is heated. 6. **Final Answer**: Therefore, the correct option is (a) always increase.
