Question
Wood burns at a temperature of approximately 500. °C. One cord of seasoned (dry) firewood
releases approximately 2.0 X 1010 J of energy when it is burned. All the energy is delivered to the
room at approximately 20. °C. What is the change in the entropy of the wood? The change in the
entropy of the air in the room? The total change in entropy of the wood–air system?
