(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

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?

2. Relevant equations

ΔS=∫dQ/T

ΔS_universe = ΔS_surroundings + ΔS_system

3. The attempt at a solution

so it's just (-100/900)+(100/300) = 9/2 right? Just checking!
