Question

Within an insulated system, 450.6 kJ of heat is conducted through a copper rod from a hot reservoir at +200.0°C to a cold reservoir at +100.0°C. (The reservoirs are so big that this heat exchange does not change their temperatures appreciably.) What is the net change in entropy of the system?

Step 1

- Heat conducted (Q) = 450.6 kJ - Temperature of hot reservoir (T_hot) = 200.0°C = 200.0 + 273.15 = 473.15 K - Temperature of cold reservoir (T_cold) = 100.0°C = 100.0 + 273.15 = 373.15 K Show more…
