Two large reservoirs, H and C, are available: if H is at 900 K and C is at 300 K, what is the
entropy change of the Universe if 100 J of heat are taken from H and added to C?
ΔS_universe = ΔS_surroundings + ΔS_system
The Attempt at a Solution
so it's just (-100/900)+(100/300) = 9/2 right? Just checking!
