The surface of the Sun is approximately at 5 700 K, and the temperature of the Earth’s surface is approximately 290 K. What entropy change occurs when 1 000 J of energy is transferred by heat from the Sun to the Earth?
Added by Donna C.
Step 1
The formula for entropy change is ΔS = Q/T, where Q is the heat transferred and T is the temperature. For the Sun, ΔS_sun = -1000 J / 5700 K = -0.175 J/K. The negative sign indicates that the entropy of the Sun decreases as it loses heat. Show more…
