⚠️ Common Exam Traps & Conceptual Pitfalls

Students often equate a finite‑conductivity container with an isothermal change and claim the process must be isothermal; they forget that a sudden (fast) compression limits heat exchange, so the gas *may* behave adiabatically but is not forced to be so.

A gas kept in a container of finite conductivity is suddenly compressed. The process

Multiple Choice Options

  • A must be very nearly adiabatic
  • B must be very nearly isothermal
  • C may be very nearly adiabatic
  • D may be very nearly isothermal

Step-by-Step Verified Solution

**Answer:** (c) may be very nearly adiabatic. **Step-by-Step Explanation:** A sudden compression is fast, so heat exchange is negligible. The process may be nearly adiabatic if the compression is rapid.
