⚠️ Common Exam Traps & Conceptual Pitfalls

Students often think heating a sheet makes the hole shrink, forgetting that thermal expansion acts on every dimension of the material, including the empty region; the sheet’s dimensions increase uniformly, so the hole’s diameter grows proportionally with the sheet.

Multiple Choice Options

  • A gets larger
  • B gets smaller
  • C retains its size
  • D is deformed

Step-by-Step Verified Solution

**Answer:** (a) gets larger. **Step-by-Step Explanation:** When a metal sheet with a circular hole is heated, the entire sheet expands uniformly. The hole also expands, so its diameter increases. This is a standard result of thermal expansion.
