- 1. ENTROPY Reporter: KIM BURNS
- 2. What is Entropy? ?
- 3. Entropy is the measure of disorder.
- 4. PROBLEM What is the change of entropy of 1 kg of ice that is melted reversibly at 0°C and converted to water at 0°C? The heat of fusion of water is 𝐿 𝑓 = 3.34 x 105 J/kg.
- 5. Entropy in Reversible Processes.
- 6. Integrate for the entire process
- 7. PROBLEM One kilogram of water at 0°C is heated to 100°C. Compute its change in entropy. Assume that the specific heat of water is constant at 4190 J/kg.K over this temperature range.
- 8. PROBLEM A gas expands adiabatically and reversibly. What is its change in entropy?
- 9. Entropy in Cyclic Processes.
- 10. PROBLEM A Carnot engine takes 2000 J of heat from a reservoir at 500 K, does some work, and discards some heat to reservoir at 350 K. What is the total entropy change during one cycle?
- 11. Entropy in Irreversible Processes.
- 12. PROBLEM Suppose 1.00 kg of water at 100°C is placed in thermal contact with 1.00 kg of water at 0°C. What is the total change in entropy? Assume that the specific heat of water is constant at 4190 J/kg.K over its temperature range.
- 13. FIN! Any questions?
