The surface of the Sun is at approximately 5700 K and the temperature of the Earth's surface is about 290 K. What total entropy change occurs when 1000 J of heat energy is transferred from the sun to the earth? a. 2.89 J/K b. 3.27 J/K c. 3.62 J/K d. 3.97 J/K I don't know what formula to use. I tried heat transfer deltaS = mcln(T/(T+deltaT)) but I don't know know what to use for mc?! Pretty confused. Thanks for any help!
