The surface of the Sun is at approximately 5 700 K and the temperature of the Earth's surface is about 290 K.What total entropy change occurs when 1 175 J of heat energy is transferred from the Sun to the Earth?

Question

Quizplus · Accepted Answer

The total entropy change is given by ΔS = Q/T, where Q is the heat energy transferred and T is the temperature of the heat reservoir. For the Sun, T = 5700 K, and for the Earth, T = 290 K. Therefore, ΔS = Q/5700 - Q/290 = 3.85 J/K. The correct answer is B.

The Surface of the Sun Is at Approximately 5 700
