Challenge Problems

Push your limits with challenges.

Question 1

A scientist observes a material and finds it to have an entropy of 5 J/K at room temperature. They cool it to near absolute zero. How would you expect its entropy to change? Explain the principles guiding your reasoning.

💡 Hint: Consider the implications of cooling on molecular arrangement.

Question 2

Assuming a certain crystalline structure maintains a fixed lattice arrangement at absolute zero, calculate the change in entropy if it were to be heated to 100 K, causing a vibrational state. Provide an entropy change estimation.

💡 Hint: Use entropy change formulas, and think about how temperature affects molecular movement.
