⚠️ Common Exam Traps & Conceptual Pitfalls

Students often assume thermal equilibrium demands direct contact, overlooking heat transfer by radiation or through a surrounding medium; remember that equilibrium is defined solely by equal temperature, which can be achieved without touching.

Is it possible for two bodies to be in thermal equilibrium if they are not in contact?

Step-by-Step Verified Solution

**Answer:** Yes, two bodies can be in thermal equilibrium without being in contact. **Step-by-Step Explanation:** Two bodies can reach the same temperature without touching, e.g., by exchanging heat through radiation or through an intermediate medium. Thermal equilibrium is a state (equal temperature), not a process. Contact is not required.
