The sun is approximately 27,000 light years away from the center of our galaxy.
The entropy change<span> of the surroundings is driven by heat flow and the heat flow determines the sign of ΔS</span>surr<span>. It can be calculated by the following expression:
</span>ΔSsurr = -(ΔH) / T
We calculate as follows:
ΔSsurr = -13200 / 1337 = 9.87 J/ K mol
Hope this answers the question. Have a nice day.
