SUMMARY
The discussion centers on calculating the change in entropy when heat leaks from a house. Given the internal temperature of 19.2° C and an external temperature of 10.7° C, the heat loss of 5.49 kJ results in a calculated entropy change of 0.01935 kJ/K. However, the correct approach requires considering both the entropy loss inside the house and the entropy gain outside, leading to a total change in entropy of 0.56293 J/K, which was confirmed as correct by the Webassign system.
