⚠️ Common Exam Traps & Conceptual Pitfalls

Students often assume that supplying heat ($Q > 0$) always results in a temperature rise ($\Delta T > 0$), ignoring that during a phase transition (like melting), the added energy is consumed as latent heat, causing the temperature to remain constant despite continuous heat input.

If heat is supplied to a solid, its temperature:

Multiple Choice Options

  • A must increase
  • B may increase
  • C may remain constant
  • D may decrease

Step-by-Step Verified Solution

**Answer:** b), c), d) may happen. **Step-by-Step Explanation:** If heat is supplied to a solid, its temperature may increase, may remain constant (during phase change), or may decrease (if it's doing work or undergoing an endothermic process).
